Targeted Cognitive Training's Effects on Real-World Cognition in Individuals at High Risk for Psychosis
Creators: name: Galindo, Briana N.
Publisher: name: University of Illinois Chicago
Year: 2025

description: Individuals at clinical high risk for psychosis (CHRp) often experience cognitive and social cognitive impairments, leading to functional difficulties that affect their quality of life. Although interventions have been developed to address these issues, current functioning measures have not been successful in capturing the global and social functioning abilities of CHRp participants. This research study aims to investigate whether Targeted Cognitive Training (TCT) can improve the daily reports of cognitive difficulties and social cognitive abilities of individuals at clinical high risk for psychosis, as compared to a control condition.
The study had 64 participants, 32 in the treatment group and 32 in the control group. They were required to complete daily diaries before, during, and after a cognitive training program (TCT) and during a 9-month follow-up. The training sessions were accessed using the PositScience IOS app, and the participants completed them in 8-12 weeks. An exploratory factor analysis was conducted to determine the dimensionality of the scales from the daily diary data. A Structural Equation Model (SEM) was run to understand the differences in real-world cognition and real-world social cognition reported in the daily diaries at four different time points between the two groups (Training and Control).
The study found no significant differences in self-report real-world cognition and real-world social cognition between the treatment and control groups during or after TCT. Therefore, the EMS approach used in this study was not sufficiently sensitive to measure a change in functioning in CHRp. In the Discussion, we provide some suggestions for improving these measures.
Unpacking Writer Identity: How Beliefs and Practices Inform Writing Instruction
Creators: name: Premont, David
Publisher: name: Purdue University Graduate School
Year: 2021
Subjects: Teacher education and professional development of educators

description: The purpose of this study is to explore the writer identity of four preservice teachers from a large midwestern University. I utilized the narrative inquiry methodology. I interviewed participants four times: Once in January 2019, January 2020, March 2020, and May 2020. I also asked participants to submit a visual metaphor and reflection. Additionally, I observed participants teach in the secondary classroom. Primarily, the findings reveal that participant writer identities largely influence their secondary writing pedagogy. The findings also indicate that participant writer identities were strongly influenced by their k-12 English teachers. Lastly, the findings suggest that participants experienced trouble navigating tensions in writing instruction. The implications suggest that teacher educators can highlight identity work in teacher education courses to strengthen writer identity. Similarly, I recommend in the Implications section that teacher educators design activities to strengthen preservice teachers’ writer identities so they can strengthen the writer identity of future secondary students. The implications also underscore how teacher educators can highlight the tensions that preservice teachers may encounter as a secondary writing instructor, and how to navigate such tension. This study complements the research on writing teacher education and provides new possibilities to effectively prepare writing instructors.
Scalable Operational Traffic Signal Performance Measures from Vehicle Trajectory Data

Subjects: Transport engineering
Autonomous vehicle systems

description: Operations-oriented traffic signal performance measures are important for identifying retiming needs to improve traffic signal operations. Enhancements on traffic signal timings can lead to a decrease on delays, fuel consumption, and air pollutants.
Currently, most traffic signal performance measures are obtained from high-resolution traffic signal controller event data, which provides information on an intersection-by-intersection basis and requires significant initial capital investment. Further, maintenance of the required sensing and communication equipment can represent a significant cost.
Over 400 billion vehicle trajectory points are generated each month in the United States. This high volume of data provides more than 95% of road network coverage. This thesis proposes using vehicle trajectory data to produce traffic signal performance measures such as: traditional Highway Capacity Manual (HCM) Level of Service (LOS), quality of progression, split failure, and downstream blockage.
Geo-fences are created at specific signalized intersections to filter vehicle’s waypoints that lie within the generated boundaries. These waypoints are then converted into trajectories that are relative to the intersection. Subsequently, trajectory attributes, such as delay and location and number of stops, are analyzed to produce the mentioned performance measures.
A case study is presented to demonstrate the methodology, which summarizes the performance of an 8-intersection corridor with 4 different timing plans using over 117,000 trajectories and 1.5 million GPS samples collected during weekdays in July 2019. Graphics to analyze entire corridors and to effectuate temporal comparisons are proposed.
The thesis concludes by discussing the required effort and recommendations for scalability, cloud-based implementation opportunities and costs, reviewing current probe data penetrations rates, and indicating that these techniques can be applied to corridors with Annual Average Daily Traffic (AADT) of ~15,000 vehicles-per-day (VPD) for the mainline approaches.

Mechanism-Driven, Physiologically-Based Pharmacokinetic Modelling of Oral and Subcutaneous Administration
Creators: name: Zheng, Fudan
Publisher: name: Purdue University Graduate School
Year: 2021
Subjects: Pharmaceutical sciences

description: Physiologically-based pharmacokinetic (PBPK) modeling is a mathematical tool to assess the adsorption, distribution, metabolism and excretion (ADME) process of drug inside the body. Drug absorption kinetics is commonly modeled using empirical compartment-based model, which hinders the interpretation of the role of formulation attributes on the in vivo fate of drug. This work elucidates the development and application of two mechanistic absorption models for: (i) oral delivery of small molecule; (ii) subcutaneous (SC) delivery of macromolecule. In the first part, PBPK model was employed to identify the potential reasons of severe bleeding when patients interchange brands of warfarin sodium tablets. The phase transition process was developed into the advanced compartmental absorption and transit (ACAT) model, which was coupled with population pharmacokinetic and pharmacodynamics (PKPD) model to explore the formulation impacts of warfarin sodium tablet on its therapeutic performance. Dissolution, precipitation, gastric transit and absorption kinetics of warfarin in gastrointestinal (GI) tract were well captured by the integrated model. The simulated PK and international normalized ratio (INR) are in line with clinical observations. Mean particle size and chiral ratio were identified as the critical attributes that may substantially increase hemorrhagic risks. In the second part, a multiphysics SC tissue model was implemented to account for tissue displacement, interstitial fluid flow and drug mass transport following SC injection. Spatiotemporal evolution of tissue deformation, porosity rise, pressure buildup and interstitial fluid velocity increase were observed during the injection stage of albumin. The simulated local absorption kinetics of albumin and IgG align well with the radiolabeled studies. Intrinsic tissue porosity, lymphatic vessel density, drug partition coefficient and hydraulic conductivity play important roles in local absorption process. The established SC absorption model was further integrated into the minimal PBPK (mPBPK) model to simulate drug transport from the injection site into the systemic distribution. The presystemic catabolism when drug transports through the posterior lymphatics was also modeled. Local absorption rate and presystemic clearance of therapeutic monoclonal antibodies (mAbs) were found to be correlated with the positive charge in the complementarity-determining region (CDR) and protein stability propensity, respectively. The abovementioned two PBPK platforms with mechanistic absorption models draw insights into predicting the impacts of physiochemical properties of drug molecule and physiological conditions of human population on the PKPD profiles.

description: A $q$-bic form is a pairing $V \times V \to \mathbf{k}$ that is linear in the second variable and $q$-power Frobenius linear in the first; here, $V$ is a vector space over a field $\mathbf{k}$ containing the finite field on $q^2$ elements. This article develops a geometric theory of $q$-bic forms in the spirit of that of bilinear forms. I find two filtrations intrinsically attached to a $q$-bic form, with which I define a series of numerical invariants. These are used to classify, study automorphism group schemes of, and describe specialization relations in the parameter space of $q$-bic forms.

description: In conditions of financial instability, companies are faced with the need to maintain staff efficiency with limited resources. Revenue reduction, salary freezes, reduction of bonuses and social benefits have a negative impact on employee morale, which entails a drop in productivity and an increase in staff turnover. However, it is precisely during a crisis that the role of non-material motivation increases, and management is obliged to seek flexible and non-standard approaches to stimulating the team.

Subjects: subject: migration, asylum, faith-based organisations, tragedy, borders, dialectics, Gillian Rose, Henri Lefebvre

description: This research articulates a dialectical theory of the border. It argues that the border should be viewed as a ‘concrete abstraction’ that is at once reified as an ideal object, and extends both spatially and temporally to bear down on the concrete experience of day-to-day life in divisive and often malign ways. The research explores the tragedy of the border for those on whom it bears down and pushes in to destitution, and attempts to challenge this injustice.

This is an ethnographic study, and particular focus is given to the experiences of destitute asylum seekers making use of a network of night shelters provided by the Boaz Trust in Manchester, UK. The Boaz Trust is a faith-based organisation that provides accommodation, support, and advocacy to refused asylum seekers in the city and aims to ‘end asylum destitution’. Based on participant observation working in the shelters as a volunteer, time spent living in the shelters, and time alongside destitute asylum seekers on the streets of Manchester, I explore the simultaneous experience of inclusion and exclusion that characterises ‘spaces of asylum’ in the city, and of a ‘weaponised time’ marked by a bifurcated ‘waiting’; where individuals see out each day without the right to work, access public funds, or remain in the UK while also caught up in a longer term, antagonistic, and dysfunctional bureaucratic temporality. I also examine the attempts of volunteers working in the shelters to press against such injustices, exploring these attempts within an understanding of justice as coming in to being through repetitive, arduous and often banal practices of care, and as speculative, fragile and always incomplete.
DETECTION AND HEALING OF STREAKS CAUSED BY DUST IN SHEETFED SCANNERS; MOTOR CONTROL, MODEL BASED HALFTONING, AND PRINT MASK DESIGN USING DIRECT BINARY SEARCH FOR INKJET PRINTERS
Creators: name: Kenzhebalin, Daulet O
Publisher: name: Purdue University Graduate School

Subjects: Image processing

description: In this thesis, I present three research topics in the areas of scanning and printing.The first topic is on detecting and removing specific artifacts in images scanned usingsheetfed scanners. Sheetfed scanners are widely used for scanning stacks of loose pages athigh speed. The scanhead in the sheet-fed scanners is stationary and the pages are fed withan automatic document feeder. When dust particles get stuck onto the scanner glass, theyreflect the incident light and cause vertical streaks in the scanned images. These artifacts areknown as dust streaks. I have developed a method for detecting and healing dust streaks.The second topic is on motor control system and test page design for inkjet printers.Motor control consists of two main parts which are movement of the printhead in the scandirection and the process direction. Scan direction movement needs to have a constantsmooth velocity in order to avoid banding artifacts. Process direction movement needs toadvance an exact distance in order to avoid misalignment. The full procedure for implementingthe motor control on a microcontroller, determining optimal parameters, and designingtest pages for validating the motor control system is presented.The third topic is on printer model based halftoning and print mask design using DBS.Inkjet printers can fire nozzles at specific pixel locations. Due to nozzle clogging and nonuniformityin the nozzles, inkjet printers usually print in the multipass mode to reduce printartifacts. In this mode, the printhead goes over the same line more than once with differentsets of nozzles of the same ink. Print mask determines which pixels are printed at a certainpass and which pixels are not printed. I developed a printer model to predict prints andalso developed test pages to obtain parameters for the printer model. Then, we looked intomodel based halftoning and print mask design using the direct binary search algorithm. Inaddition, I investigated the advantages and disadvantages of using light magenta as opposedto using black ink in 4-color printing.

description: Early studies proposed a connection between cuprate superconductivity and fractionalized spin liquid states. But the low temperature phase diagram is dominated by states without fractionalization, with a competition between superconductivity and charge-ordered states which break translational symmetry. Our theory uncovers novel features associated with a particular spin-liquid presumed to underlie the pseudogap metal, and shows that it has multiple nearly-degenerate instabilities to confinement of fractionalized excitations, leading to antiferromagnetism, $d$-wave superconductivity, and/or charge order. Our theory provides routes to resolving a number of open puzzles on the cuprate phase diagram.
 The spin liquid is described by a SU(2) gauge theory of $N_f=2$ massless fundamental Dirac fermions, has an emergent SO(5)$_f$ global symmetry, and is presumed to confine at low energies to the Néel state. At non-zero doping (or smaller Hubbard repulsion at half-filling) we argue that confinement occurs via the Higgs condensation of bosonic chargons carrying fundamental SU(2) gauge charges moving in $π$ flux. At half-filling, the low energy Higgs sector has $N_b=2$ relativistic bosons with a possible emergent SO(5)$_b$ global symmetry describing rotations between a $d$-wave superconductor, period-2 charge stripes, and the time-reversal breaking `$d$-density wave' state. We propose a deconfined quantum critical point between a confining state which breaks SO(5)$_f$ and a confining state which breaks SO(5)$_b$. The pattern of symmetry breaking within both SO(5)s is determined by terms likely irrelevant at the critical point, which can be chosen to obtain a transition between Néel order and $d$-wave superconductivity. A similar theory applies at non-zero doping and large $U$, with longer-range couplings of the chargons leading to charge order with longer periods.

IMPROVED LIVE LOAD DISTRIBUTION FACTORS FOR USE IN LOAD RATING OF SLAB AND T-BEAM REINFORCED CONCRETE BRIDGES
Creators: name: Ravazdezh, Faezeh
Publisher: name: Purdue University Graduate School
Year: 2021
Subjects: Civil engineering not elsewhere classified

description: This study aimed to investigate potential improvements in load estimation in the standard load rating procedure of reinforced concrete slab and girder bridges. Three-Dimensional (3D) Finite Element (FE) models were used to conduct refined analyses of bridges using full-scale models that account for non-structural elements in superstructure modeling. The rating results obtained from FE analysis for a small sample of bridges indicated that Conventional Load Rating (CLR) methodology could lead to conservative rating factors mainly due to demand overestimation. A parametric study associated with demand assessment showed a substantial impact of geometric features on bridge moment and shear values. The study showed that edge-elements such as railings and end-diaphragms significantly changed the distribution of loads over the bridge width due to the edge-stiffening effect. Effects from the presence of edge components are not reflected in the methodology outlined in American Association of State Highway and Transportation Officials (AASHTO) specifications and may be a source of overestimation or underestimation of demands on bridges. Potential improvements to current live load Distribution Factor (DF) formulations were identified based on statistical studies where bridge responses subjected to standard truck load configurations obtained from FE analysis were compared to the current procedure’s corresponding results. Modification Factors (MF) to live load DF were proposed to incorporate secondary elements’ effect in demand estimates. Updated DFs could result in more accurate rating factors when used in the CLR of existing slab and T-beam bridges. This would benefit a great population of bridges conservatively rated as structurally deficient. The proposed modifications could prevent unnecessary rerouting, weight posting, bridge closure, and replacement.
The Iteration Number of the Weisfeiler-Leman Algorithm

description: We prove new upper and lower bounds on the number of iterations the $k$-dimensional Weisfeiler-Leman algorithm ($k$-WL) requires until stabilization. For $k \geq 3$, we show that $k$-WL stabilizes after at most $O(kn^{k-1}\log n)$ iterations (where $n$ denotes the number of vertices of the input structures), obtaining the first improvement over the trivial upper bound of $n^{k}-1$ and extending a previous upper bound of $O(n \log n)$ for $k=2$ [Lichter et al., LICS 2019].
 We complement our upper bounds by constructing $k$-ary relational structures on which $k$-WL requires at least $n^{Ω(k)}$ iterations to stabilize. This improves over a previous lower bound of $n^{Ω(k / \log k)}$ [Berkholz, Nordström, LICS 2016].
 We also investigate tradeoffs between the dimension and the iteration number of WL, and show that $d$-WL, where $d = \lceil\frac{3(k+1)}{2}\rceil$, can simulate the $k$-WL algorithm using only $O(k^2 \cdot n^{\lfloor k/2\rfloor + 1} \log n)$ many iterations, but still requires at least $n^{Ω(k)}$ iterations for any $d$ (that is sufficiently smaller than $n$).
 The number of iterations required by $k$-WL to distinguish two structures corresponds to the quantifier rank of a sentence distinguishing them in the $(k + 1)$-variable fragment $C_{k+1}$ of first-order logic with counting quantifiers. Hence, our results also imply new upper and lower bounds on the quantifier rank required in the logic $C_{k+1}$, as well as tradeoffs between variable number and quantifier rank.

Mithilfe von fotorealistischen, durch Künstliche Intelligenz generierten Porträts beleuchtet sie die Geschichten von siebzehn Wissenschaftlerinnen und gibt ihnen damit eine Form der Anerkennung, die ihnen zu Lebzeiten oft verwehrt blieb. Die KI-generierten Bilder holen die fehlende visuelle Würdigung nach und machen zugleich auf die weiterhin bestehende Geschlechterdiskrepanz in der Wissenschaft aufmerksam. Das Projekt reflektiert somit nicht nur historische Ungerechtigkeiten, sondern steht auch im aktuellen Diskurs um Geschlechtergerechtigkeit. Im Interview mit Julia Wustmann gibt Gesine Born Einblicke in die Entstehung und Hintergründe der Ausstellung.

Measuring Students' Knowledge Mastery Patterns in Energy Using Cognitive Diagnostic Models
Creators: name: Zhou, Shuqi
Publisher: name: Purdue University Graduate School

Subjects: Educational psychology

description: Cognitive diagnostic models can uncover students’ mastery of multiple fine-grained skill attributes or problem-solving processes. A number of studies have applied cognitive diagnostic models to detect students’ knowledge mastery in mathematics and language testing. However, few studies focus on cognitive diagnostic assessment in K-12 science education, and no studies on the energy topic specifically. This study applied cognitive diagnostic models to Trends in International Mathematics and Science Study (TIMSS) science achievement data to assess students’ knowledge mastery in energy. Three TIMSS participating jurisdictions, i.e., Australia, Hong Kong, and Ontario were compared. A Q matrix (i.e., an item attribute alignment table) was proposed based on existing literature about learning progressions of energy in the physical science domain, and the TIMSS assessment framework. The Q matrix was validated through expert review and real data analysis. Then, one of the cognitive diagnostic models, i.e., the deterministic inputs, noisy and-gate (DINA) model was applied to each jurisdiction’s data.
Results suggested that the hypothesized learning progression was consistent with Australian and Ontario students’ but not Hong Kong students’ observed progression in understanding the energy concept. According to overall attribute mastery probabilities and the latent class pattern, most students failed to explain simple electrical systems. Students also performed poorly in recognizing that heating an object can increase its temperature, and that hot objects can heat up cold objects. Identifying sources of energy was found to be easiest to be mastered. I discuss several potential curriculum-related issues that may affect students’ mastery patterns in different jurisdictions.

description: In Chapter 1, a theory of optimal fund size in venture capital is developed. Fund managers - the VCs - add value to the projects they finance, but their human capital is scarce. A matching model is proposed where VCs span their nurturing activity over more projects, and entrepreneurs, who own the projects, direct their search to VCs based on their projects’ quality. The work provides necessary and sufficient conditions for positive and negative assortative matching over VC attention and project quality to emerge and shows when VCs fundraising decision is distorted by selection considerations. The chapter ends with an investigation of the effects of entry of less skilled intermediaries. By attracting the worse entrepreneurs, these new agents alleviate the adverse selection problem associated to managing a larger fund. This offers a new angle to think about policies encouraging entry in the venture capital industry.
 In Chapter 2, the model developed in Chapter 1 is extended to a dynamic setting, where projects need time to develop and produce returns. VCs can choose to enter in a short-term contract with investors, giving them access to investors liquidity for a given period of time, and an open credit relationship that allows them to raise investors money at any point in time. The model illustrates a novel advantage of closed, finite-horizon funds, which emerge in equilibrium even when they are socially undesirable: they attract the best entrepreneurs, who value the most the exclusive relationship that only a closed-end fund can guarantee. The interpretation is that VCs benefit from committing to a size in the first place.
 In Chapter 3, the focus moves to the study of the distortions in fund managers’ behavior that may occur within a fund’s life. A setting is introduced where information about a manager’s ability is imperfect and managers are interested in their reputation. Given the application to investments in young firms, managers in the model are agents that create value because they can experiment and learn about a projects potential. Their incentive to take on risk is distorted by career concerns, and can result in under or over risk-taking. The result contrasts with Holmstrom (1999) where managers directly affect the project’s success rate, and career concerns can only produce inefficiently low risk-taking. It is shown that the inefficiency is reduced when the market can also observe the outcome of projects with the same fundamental.
title: Dialectics of the hero: representing subjectivities : On the Possibilities of Contemporary Figurative Sculpture
Creators: name: Correia Goncalves, Joao Miguel

Subjects: subject: Sculpture, Minimalism, Contemporary Figurative Sculpture, Hero, Ethico-political subject

description: This thesis sets out to critically reposition contemporary figurative sculpture through a re- articulation of the hero. 

It starts by identifying the removal of the human figure in minimal art and with notions of objectivity, repetition and indifference. Here I argue against Donald Judd, Robert Morris and Rosalind E. Krauss, by claiming that there is a necessity to reflect upon the sculptural object and the subject beyond that which is produced by the principles outlined by these artists and critics. 

Working through readings of Judith Butler, Alain Badiou, Hannah Arendt, Bernard Stiegler, Jacques Lacan and others, the argument establishes the contingency and polemics of the term hero, the way it pertains to the introduction of the new and how it coalesces action and narrative with constant negotiation. Using the philosophy of Richard Rorty as a scaffold, I propose in turn that the hero constitutes a necessary idealism for improving vocabularies, and along with Bruno Latour’s position on composition, that this can be translated into figurative sculpture as a dialectical becoming-object. 

Additionally, the problem of knowing what constitutes a subject of heroism is associated with the formation of an ethical subject. I conclude, in contrast to Simon Critchley and Jacques Derrida, that this subject can be articulated using the hero strategically as a conceit. I also suggest that, as such, it can be realized through the work of figurative sculpture and the agonist space it produces. 

Alongside this, the thesis rethinks the materiality associated with figuration in terms of construction, and elaborates on the importance of the hero to the post-mannequin condition of figurative sculpture based on how it combines invention with political determination. This is further examined by looking at the work of Isa Genzken, Rachel Harrison and Mark Manders, and especially at the practice-based component of this thesis.
title: Watching Foreign TV in an Age of Online Sharing: The cultural implications of cross-border television experience

description: In recent years, unofficial and/or illegal forms of online file sharing have been increasingly used by audiences worldwide to consume foreign TV programmes which would not previously have been available to them at the time when such shows were first broadcast in their original regions. This form of consumption shortens the time-and-space gap between foreign broadcast and local consumption, highlighting audiences’ desires for borderless, transnational viewing. Taking Taiwanese audiences as an example, this research studies the implications which transnational foreign television consumption via online sharing may bring. Based on in-depth interviews with thirty-six audience members conducted from 2010 to 2011, I focus on two issues:

1.	The meaning of television for its audiences: 

This research examines how and why audiences employ online sharing to bypass temporal, spatial and legal constraints on consuming foreign programmes, and elaborates the ways in which such consumption is becoming an emerging norm of television experience. It sheds light on how our existing understandings have changed, regarding what is meant by “watching TV”, and what television’s role is in providing a sense of liveness, shaping audiences’ sense of social togetherness and their cultural identity.

2.	Transnational media flows and cultural power relationships:

This research looks at the implications of this cross-border Taiwanese consumption of television for transnational media flows in the post-colonial East Asian contexts. It examines cultural power relationships between East Asian countries, as well as those between the East and the West. Furthermore, by elaborating how audiences’ sense of co-temporality with (and understanding of) other cultures develop via their consumption, this research analyses how such consumption shapes the direction of media flows and cultural power relationships of Taiwan with other countries and thus offers a contemporary understanding of what television means as a cultural form, and what features television audiences have, in the post-network era today.
Biogeography of the Caribbean Clades of Pitcairnia L’Her. and Wittmackia Mez (Bromeliaceae Juss.)

description: Wittmackia and Pitcairnia exhibit a disproportionate level of endemism in the Caribbean islands compared to the rest of the Bromeliaceae family. With genomics and transcriptomic tools, I explore the biogeographic history of the Caribbean clades of each genus. In both cases migration is hypothesized to have taken place from South America; for Wittmackia, the closes relatives occur in Brazil and for Pitcairnia they are in Venezuela. A rapid burst of diversification took place in Jamaica that resulted in 13 different species of Wittmackia, of the 17 that are present in this clade. Incomplete lineage sorting is evidenced by high levels of gene tree – species tree conflict and low levels of hybridization. In Pitcairnia we find a pattern of island hopping through the Lesser Antilles island arc. I found that the diversity of Pitcairnia to be overestimated in the region and propose the species in the Island of Ayiti (Hispaniola) be synonymized with P. fuertesii, and P. jareckii with P. angustifolia.

description: Beta-gallium oxide (β-Ga2O3) is an emerging wide bandgap semiconductor for next generation power devices which offers the potential to replace GaN and SiC. It has an ultra-wide bandgap (UWBG) of 4.8 eV and a corresponding Ebr of 8 MV/cm. β-Ga2O3 also possesses a decent intrinsic electron mobility limit of 250 cm2/V·s, yielding high Baliga’s figure of merit of 3444. In addition, the large bandgap of β-Ga2O3 gives stability in harsh environment operation at high temperatures. Although low-cost large-size β-Ga2O3 native bulk substrates can be realized by melt growth methods, the unique property that (100) surface of β-Ga2O3 has a large lattice constant of 12.23 Å allows it to be cleaved easily into thin and long nano-membranes. Therefore, β-Ga2O3 FETs on foreign substrates by transferring can be fabricated and investigated before β-Ga2O3 epitaxy technology becomes mature and economical viable. Moreover, integrating β-Ga2O3 on high thermal conductivity materials has an advantage in terms of suppressing self-heating effects. In this dissertation, structural and material innovations to overcome and improve critical challenges are summarized as follows: 1) Top-gate nano-membrane β-Ga2O3 FETs on a high thermal conductivity diamond substrate with record high maximum drain current densities are demonstrated. The reduced self-heating effect due to high thermal conductivity of the substrate was verified by thermoreflectance measurement. 2) Local electro-thermal effect by electrical bias was applied to enhance the electrical performance of devices and improvements of electrical properties were shown after the annealing. 3) Thin thermal bridge materials such as HfO2 and ZrO2 were inserted between β-Ga2O3 and a sapphire substrate to reduce self heating effects without using a diamond substrate. The improved thermal performance of the device was analyzed by phonon density of states plots of β-Ga2O3 and the thin film materials. 4) Nano-membrane tri-gate β-Ga2O3 FETs on SiO2/Si substrate fabricated via exfoliation have been demonstrated for the first time. 5) Using the robustness of β-Ga2O3 in harsh environments, β-Ga2O3 ferroelectric FETs operating as synaptic devices up to 400 °C were demonstrated. The result offers the potential to use the novel device for ultra-wide bandgap logic applications, specifically neuromorphic computing exposed to harsh environments.
