Determinants of Low Birth Weight in Debre Berehan Referal Hospital, North Shoa Zone, Amhara Regional State, Ethiopia (A Case – Control Study)
Creators: name: Desalegn, Lema
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Introduction: Low birth weight is defined as birth weight less than 2,500 grams. More than 20 million infants are born each year weighing less than 2500 gm, accounting for 17% of all births in the developing world. Similarly, according to Ethiopian demographic and health survey (EDHS 2011), 11% weighed less than 2500 gm. Birth weight plays an important role in infant mortality and morbidity, development, and future health of the child. Weight at birth is directly influenced by general level of health status of the mother. Objectives: The main objective of the study is to identify determinants of low birth weight in Debre Berehan Referral hospital. Methodology: The study was a facility based unmatched case-control study design conducted by reviewing cards of mothers and neonates who delivered in Debre Berehan Referral hospital just three years back from study period (February to June 2015). Data analysis was done by SPSS version 20 and bivariate and multivariate statistical methods were used. RESULT: In this study 441 mothers and newborns cards were included yielding 100 % response rate. From this 147 mothers and newborn cards were selected for case group and 294 mothers and newborn cards were selected for control group .The mean birth weight was 2077.55gm (S.D±325.78 gm) for the neonates with low birth weight and 3230.0 (S.D±449.73 gm) for the neonates with normal birth weight. Out of 441 mothers in both case and control groups, most of them were between the age group of 21-25 years, which is 39.5% and 36.1% for case group and control group, respectively. Those newborns with gestational age less than 37 weeks were 4 times (AOR=4, 95%CI (1.61,8.13) p-value =0.0001) more likely to be delivered low birth weight than those new born greater than or equal to 37 weeks of gestation. So, significant association is found between gestational age and BW. Pregnancy induced hypertension (AOR =3.415, 95% CI (0.855, 13.645 p-value 0.047) have significant association. Another variable that have significant association with BW is hemoglobin level (AOR 1.0, 95% CI (1.0, 1.0) p-value =0.045). Conclusion: According to the findings of this study the determinant factors for LBW are: Gestational age less than 37 weeks, hemoglobin level of the blood, PIH. So that interventions to prevent pre term, control blood hemoglobin level of the mothers, prevent anemia and prevent hypertension are important to manage LBW. Key words: low birth weight, maternal factors, case control, Debre Berehan.
Essays on Hybrid Modeling of Machine Learning Algorithms and Financial Time Series Models

description: This thesis attempts to model and forecast realized volatility and stock market tail risk using hybrid models integrating Machine Learning algorithms with Financial Time Series models. One of the advantages of Machine Learning approaches is that it can well approximate a wide range class of linear and nonlinear functions, forming the input-output map by learning the data rather than assuming the data generating process. Traditional Time Series models, however, focus on reproducing the stylized facts of target variables through statistical modeling. By hybriding these two types of models, we find that Machine Learning approaches well complement Financial Time Series models in variable screening, complex relationship detection and nonlinearity modeling. In addition, it is found that instead of using raw data in the Machine Learning algorithms, Financial Time Series models generate more effective features that significantly improves learning ability of those algorithms.

description: Hwang's quasi-power theorem asserts that a sequence of random variables whose moment generating functions are approximately given by powers of some analytic function is asymptotically normally distributed. This theorem is generalised to higher dimensional random variables. To obtain this result, a higher dimensional analogue of the Berry-Esseen inequality is proved, generalising a two-dimensional version by Sadikova.

description: We study the molecular gas properties of high-$z$ galaxies observed in the ALMA Spectroscopic Survey (ASPECS) that targets a $\sim1$ arcmin$^2$ region in the Hubble Ultra Deep Field (UDF), a blind survey of CO emission (tracing molecular gas) in the 3mm and 1mm bands. Of a total of 1302 galaxies in the field, 56 have spectroscopic redshifts and correspondingly well-defined physical properties. Among these, 11 have infrared luminosities $L_{\rm{}IR}>10^{11}$ L$_\odot$, i.e. a detection in CO emission was expected. Out these, 7 are detected at various significance in CO, and 4 are undetected in CO emission. In the CO-detected sources, we find CO excitation conditions that are lower than typically found in starburst/SMG/QSO environments. We use the CO luminosities (including limits for non-detections) to derive molecular gas masses. We discuss our findings in context of previous molecular gas observations at high redshift (star-formation law, gas depletion times, gas fractions): The CO-detected galaxies in the UDF tend to reside on the low-$L_{\rm{}IR}$ envelope of the scatter in the $L_{\rm{}IR}-L'_{\rm{}CO}$ relation, but exceptions exist. For the CO-detected sources, we find an average depletion time of $\sim$ 1 Gyr, with significant scatter. The average molecular-to-stellar mass ratio ($M_{\rm{}H2}$/$M_*$) is consistent with earlier measurements of main sequence galaxies at these redshifts, and again shows large variations among sources. In some cases, we also measure dust continuum emission. On average, the dust-based estimates of the molecular gas are a factor $\sim$2-5$\times$ smaller than those based on CO. Accounting for detections as well as non-detections, we find large diversity in the molecular gas properties of the high-redshift galaxies covered by ASPECS.

description: Nowadays, experimental techniques allow scientists to have access to large amounts of data. In order to obtain reliable information from the complex systems which produce these data, appropriate analysis tools are needed}. The Kalman filter is a {frequently used} technique to infer, assuming a model of the system, the parameters of the model from uncertain observations. A well-known implementation of the Kalman filter, the Unscented Kalman filter (UKF), was recently shown to be able to infer the connectivity of a set of coupled chaotic oscillators. {I}n this work, we test whether the UKF can also reconstruct the connectivity of {small groups of} coupled neurons when their links are either electrical or chemical {synapses}. {In particular, w}e consider Izhikevich neurons, and aim to infer which neurons influence each other, considering {simulated spike trains as the experimental observations used by the UKF}. First, we {verify} that the UKF can recover the parameters of a single neuron, even when the parameters vary in time. Second, we analyze small neural ensembles and}} demonstrate that the UKF allows inferring the connectivity between the neurons, even for heterogeneous, directed, and {temporally evolving} networks. {Our results show that time-dependent parameter and coupling estimation is possible in this nonlinearly coupled system.

description: We provide the first example of a communication model and a distributed task, for which there exists a realistic quantum protocol which is asymptotically more efficient than any classical protocol, both in the communication and the information resources. For this, we extend a recently proposed coherent state mapping for quantum communication protocols, introduce the notion of multiplexed coherent state fingerprints and show how to use them to design an efficient quantum protocol for estimating the Euclidean distance of two real vectors within a constant factor.

description: The Mariana forearc provides a unique natural laboratory to study slab dehydration in an active subduction zone by its deep-rooted mud volcanism. To test if mantle wedge serpentinites would record the source fluid composition and thus the dehydration reactions in the slab, we investigated silicon (Si) isotopic compositions (δ30Si) in serpentine veins by in-situ femtosecond laser ablation ICP mass spectrometry. Our samples were recovered during IODP Expedition 366 and originate from three mud volcanoes that root in different depths, so that the pressure/temperature conditions in their source regions vary. The δ30Si values differ strongly between the mud volcanoes but also between different serpentine generations within individual samples. Serpentine that formed under low water/rock ratios has δ30Si similar to pristine olivine. In contrast, serpentine veins that formed under higher water/rock ratios show large ranges in δ30Si that vary significantly but systematically between the mud volcanoes and thus with the metamorphic grade at depth. Average δ30Si of such serpentine veins are ‑0.10 ‰, ‑1.94 ‰, and ‑0.80 ‰ to ‑0.93 ‰ with increasing depth-to-slab. We interpret these across-forearc changes to record the Si isotopic compositions of the fluid sources, that are at shallow depth (inferred slab temperatures of ~80°C) the dehydration of (biogenic) opal and release of pore fluids, at intermediate depth (~150°C) clay mineral breakdown, and at the deepest point (>250°C) decomposition of clay minerals and altered oceanic crust. These data imply that Si isotope signatures of wedge serpentinites can be used as a reliable proxy for slab dehydration processes.

description: Salah satu syubhat (kerancuan) yang disebarkan oleh orang-orang yang memiliki niat buruk untuk menyebarkan keraguan dalam aqidah adalah mempersoalkan penggunaan kata ganti “Kami” untuk lafazh Allah ta’ala dalam Al-Qur’an. Bila diteliti secara mendalam, penggunaan dhamir mutakallim (pihak pertama) oleh Allah dalam Al-Qur’an, kadang menggunakan kata ganti “Aku” dan terkadang menggunakan kata ganti “Kami” ternyata memiliki sejumlah alasan ilmiah. Pada saat Allah ta’ala melakukan sendiri suatu tindakan, maka Allah pasti menggunakan kata ganti “Aku”. Semua umat Islam, baik dari kalangan Ahlus Sunnah wal Jama’ah maupun aliran-aliran yang menyimpang daripadanya tidak ada yang menafsirkan keesaan Allah dengan doktrin “Esa tapi berbilang”. Sehingga tuduhan orang-orang yang suka menyebarkan syubhat tersebut dengan berdalih pada penggunaan kata ganti “Kami” oleh Allah dalam Al-Qur’an tidak berdasar sama sekali.

description: This study intended to draw a correlational analysis between Work Life Balance and Organizational Commitment among the nurses in a tertiary hospital in Las Vegas. The research design utilized a quantitative non-experimental descriptive correlational approach. The target population are full time registered nurses who are currently employed and who have worked for at least six months with the organization. Convenience sampling was used to select participants for the survey. Work Life Balance, which is the independent variable, was measured using the Work Life Balance Measure by Brought et al (2014) and Organizational Commitment, which is the dependent variable, was assessed using Allen and Meyer’s Organizational
 Commitment Scale also known as the Three Component Model (TCM) of Employee Commitment (EC). The research used descriptive statistics in analyzing demographic data and inferential statistics to draw correlations between the variables. When it comes to health care professionals in general, previous research indicate a direct correlation between work life balance and organizational commitment.

description: Peculiar groups of X-ray emitting isolated neutron stars, which include magnetars, the "Magnificent Seven", and central compact objects in supernova remnants, escape detection in standard pulsar surveys. Yet, they constitute a key element in understanding the neutron star evolution and phenomenology. Their use in population studies in the galactic scale has been hindered by the scarcity of their detection. The all-sky survey of eROSITA on-board the forthcoming Spectrum-RG mission has the unique potential to unveil the X-ray faint part of the population and constrain evolutionary models. To create a forecast for the four-year all-sky survey, we perform Monte Carlo simulations of a population synthesis model, where we follow the evolutionary tracks of thermally emitting neutron stars in the Milky Way and test their detectability. In this work, we discuss strategies for pinpointing the most promising candidates for follow-up observing campaigns using current and future facilities.

The behaviors of the wave functions of small molecules with negative kinetic energies

Publisher: name: arXiv
Year: 2023
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: According to relativistic quantum mechanics, particles can be of negative kinetic energies (NKE). The author asserts in his previous works that the NKE substances are dark matters. Some NKE particles, say a pair of NKE electrons, can constitute a stable system by means of the repulsive interaction between them. In the present work, two simplest three-particle systems are investigated. One consists of two NKE positrons and one NKE proton, called dark hydrogen anion. The other is composed of two NKE protons and one NKE positron, called dark hydrogen molecule cation. They are so named because the Hamiltonians of them can correspond to those of the hydrogen anion and hydrogen molecule cation. In evaluating the dark hydrogen molecule cation, the famous Born-Oppenheimer approximation does not apply, i.e., the NKE of the protons cannot be neglected. Without the NKE, the system cannot be stable. Our study reveals that in a NKE system, the particles with the same kind of electric charge combine tightly. This is to enhance the repulsive Coulomb potential so as to raise the total energy as far as possible. A great amount of NKE particles can compose a dense and dark macroscopic NKE body. Thus, it is conjectured that some remote dark celestial bodies may be NKE ones other than the well-known black holes. The discrepancies between the black holes and macroscopic NKE bodies are pointed out.

Design and Analysis of GUI For Train Traffic Control Case of ERC
Creators: name: Yitagesu, Hailmichael
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Centralized Traffic Control, commonly named CTC, is the most common way nowadays of controlling train traffic. It is based on the principle of centralizing all information concerning railroad tracks over a given area and to control trains running on it by the mean of a single person, the train dispatcher. This technology needs efficient telecommunications as the employee who dispatches trains is not physically present at a station but more commonly at a remote place, namely the CTC office. The CTC retrieves railway signals and gives useful information to the train dispatcher using good design Graphical User Interface. Although it was a completely hardware device, CTC is now most of the times a software which summarizes signals, headways and trains to allow the train dispatcher taking good decisions, particularly when some trains stop or have delay. Some of CTC are even partially automatic and can take routine decisions by themselves, letting only critical decisions for human control. It also most of the times prevent human errors by avoiding decisions which could result in train collisions. This thesis objective is to design and analysis of Graphical User Interface for Train traffic control system for Ethiopian Railway Corporation. In this context, the CTC is the run time user interface and alarm handling facility for the stationary part of the system, subsystem for Centralized Traffic Control. Therefore, based on international standard graphical user interface design process, this thesis will provide analysis by compare and contrast selected candidate frameworks. One of the candidate framework will be current ERC GUI framework. And based on its merits and demerits the report will recommend an appropriate framework using standard specifications.
A theory of dark energy that matches dark matter

Publisher: name: arXiv
Year: 2023
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: In this paper, a theory of dark energy is proposed that matches dark matter. The relativistic quantum mechanics equations reveal that free particles can have negative energies. We think that the negative energy is the dark energy which behaviors as dark photons with negative energies. In this work, the photon number states are extended to the cases where the photon number can be negative integers, called negative integer photon states, the physical meaning of which are that the photons in such a state are of negative energy, i.e., dark photons. The dark photons constitute dark radiation, also called negative radiation. The formulism of the statistical mechanics and thermodynamics of the dark radiation is presented. This version of dark energy is of negative temperature and negative pressure, the latter regarded as responsible for the accelerate expansion of the universe. It is believed that there is a symmetry of energy-dark energy in the universe. In our previous work, the theory of the motion of the matters with negative kinetic energy was presented. In our opinion, the negative kinetic energy matter is dark matter. In the present work, we demonstrate that the dark substances absorb and release dark energy. In this view, the dark matter and dark energy match. Therefore, there is a symmetry of matter-energy match and dark matter-dark energy match in the universe. We present the reasons why the negative kinetic energy systems and negative radiation are dark to us.
Assessment of Nurses' Perceived Barriers for The Provision of Developmental Care in The Neonatal Intensive Care Units of Governmental Hospitals in Addis Ababa, Ethiopia

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Background: Every year, 120,000 newborns die in Ethiopia. Neonatal deaths now account for a greater proportion of under-five deaths. An estimated 3.1 million neonates die each year globally and 99% of these deaths occur in low-income countries. Despite the extraordinary improvements in child survival over the past 25 years, there is still virtually no effective health care for newborns in many developing countries. The nurse becomes the infant's primary supportive staff with the most contact with infants and their caregivers. In this study, the nurse's perceived barriers in the provision of neonatal developmental care are assessed. Objective: To assess Nurses' Perceived Barriers for the Provision of Developmental Care in the Neonatal Care Units of Public Hospitals in Addis Ababa, Ethiopia. Methods: quantitative cross sectional study was conducted. Self-administered questionnaire was used to assess nurses' perceived barriers in the provision of neonatal developmental care in all public hospitals of Addis Ababa, Ethiopia. All neonatal Nurses' working in all public hospitals of Addis Ababa was included in the study without taking sample. Binary and multiple logistic regressions were done to assess association between variables. Result: A total of 90 respondents responded to the questionnaires, giving a response rate of 97.83%. The majority of respondents were female (80%). Majority of the respondents had year of experience between 1-5 year accounting 65(7.77%). Majority of respondents 72(80%) had positive perception (accept nurses perception influence provision of NICU developmental care). Most of the respondents accept as motivation, emotion, job satisfaction, work experience, and recognition by managers and level of education affects Nurses perception in provision of NICU developmental care. Conclusion: In multiple logistic regressions job satisfaction affects the perception of Nurses in providing NICU developmental care

description: The third-order optical nonlinearity in optical waveguides has found applications in optical switching, optical wavelength conversion, optical frequency comb generation, and ultrafast optical signal processing. The development of an integrated waveguide platform with a high nonlinearity is therefore important for nonlinear integrated photonics. Here, we report the observation of an enhancement in the nonlinearity of an air-cladding silicon pedestal waveguide. We observe enhanced nonlinear spectral broadening compared to a conventional silicon-on-insulator waveguide. At the center wavelength of 1555 nm, the nonlinear-index coefficient of air-cladding silicon pedestal waveguide is measured to be about 5% larger than that of a conventional silicon-on-insulator waveguide. We observe enhanced spectral broadening from self-phase modulation of an optical pulse in the pedestal waveguide. The interaction of light with the confined acoustic phonons in the pedestal structure gives rise to a larger nonlinear-index coefficient. The experimental results agree well with the theoretical models.

description: In this paper we use ASPECS, the ALMA Spectroscopic Survey in the {\em Hubble} Ultra Deep Field (UDF) in band 3 and band 6, to place blind constraints on the CO luminosity function and the evolution of the cosmic molecular gas density as a function of redshift up to $z\sim 4.5$. This study is based on galaxies that have been solely selected through their CO emission and not through any other property. In all of the redshift bins the ASPECS measurements reach the predicted `knee' of the CO luminosity function (around $5\times10^{9}$ K km/s pc$^2$). We find clear evidence of an evolution in the CO luminosity function with respect to $z\sim 0$, with more CO luminous galaxies present at $z\sim 2$. The observed galaxies at $z\sim 2$ also appear more gas-rich than predicted by recent semi-analytical models. The comoving cosmic molecular gas density within galaxies as a function of redshift shows a factor 3-10 drop from $z \sim 2$ to $z \sim 0$ (with significant error bars), and possibly a decline at $z>3$. This trend is similar to the observed evolution of the cosmic star formation rate density. The latter therefore appears to be at least partly driven by the increased availability of molecular gas reservoirs at the peak of cosmic star formation ($z\sim2$).

description: Gradient boosted trees (GBTs) are ubiquitous models used by researchers, machine learning (ML) practitioners, and data scientists because of their robust performance, interpretable behavior, and ease-of-use. One critical challenge in training GBTs is the tuning of their hyperparameters. In practice, selecting these hyperparameters is often done manually. Recently, the ML community has advocated for tuning hyperparameters through black-box optimization and developed state-of-the-art systems to do so. However, applying such systems to tune GBTs suffers from two drawbacks. First, these systems are not \textit{model-aware}, rather they are designed to apply to a \textit{generic} model; this leaves significant optimization performance on the table. Second, using these systems requires \textit{domain knowledge} such as the choice of hyperparameter search space, which is an antithesis to the automatic experimentation that black-box optimization aims to provide. In this paper, we present SigOpt Mulch, a model-aware hyperparameter tuning system specifically designed for automated tuning of GBTs that provides two improvements over existing systems. First, Mulch leverages powerful techniques in metalearning and multifidelity optimization to perform model-aware hyperparameter optimization. Second, it automates the process of learning performant hyperparameters by making intelligent decisions about the optimization search space, thus reducing the need for user domain knowledge. These innovations allow Mulch to identify good GBT hyperparameters far more efficiently -- and in a more seamless and user-friendly way -- than existing black-box hyperparameter tuning systems.

description: One of the most fundamental topics of exobiology concerns the identification of stars with environments consistent with life. Although it is believed that most types of main-sequence stars might be able to support life, particularly extremophiles, special requirements appear to be necessary for the development and sustainability of advanced life forms. From our study, orange main-sequence stars, ranging from spectral type late-G to mid-K (with a maximum at early-K), are most promising. Our analysis considers a variety of aspects, including (1) the frequency of the various types of stars, (2) the speed of stellar evolution their lifetimes, (3) the size of the stellar climatological habitable zones (CLI-HZs), (4) the strengths and persistence of their magnetic dynamo generated X-ray - UV emissions, and (5) the frequency and severity of flares, including superflares; both (4) and (5) greatly reduce the suitability of red dwarfs to host life-bearing planets. The various phenomena show pronounced dependencies on the stellar key parameters such as effective temperature and mass, permitting the assessment of the astrobiological significance of various types of stars. Thus, we developed a "Habitable-Planetary-Real-Estate Parameter" (HabPREP) that provides a measure for stars that are most suitable for planets with life. Early K stars are found to have the highest HabPREP values, indicating they may be "Goldilocks" stars for life-hosting planets. Red dwarfs are numerous, having long lifetimes, but their narrow CLI-HZs and hazards from magnetic activity make them less suitable for hosting exolife. Moreover, we provide X-ray - FUV irradiances for G0 V - M5 V stars over a wide range of ages.

description: Geometric design is an essential and major component in the design development of railway projects. Geometric alignments (horizontal and vertical) affect project cost and safety significantly keeping other factors constant. The effect of track alignment on cost of awash-weldiya railway project in particular to Lot-11 stretch is evaluated in this thesis. Three different horizontal and vertical alignments are designed and their respective costs computed and compared. In the design process, topographic data is generated from 30m Resolution Digital Elevation Model using Global Mapper software. Horizontal and vertical alignments are designed using widely applicable Bentley Rail Track (BRT) software. In this thesis, Ethiopian Railways Corporation manual is used as governing rail standard. Basic techniques are applied for economical and safe design of the project. Generally, a minimum curve radius of 2000m and a maximum gradient of 2% is applied but a deviation from the standard is made in some parts due to topographic and other constraints. Accordingly, horizontal curves as low as 500m and gradient as high as 2.5% have been used in some places where there is topography constraint. The main parameters that are considered to evaluate the impact of track alignment on cost of the project are: earth work quantity, length of project, tunnel length, length of swampy section, total number of structures and total span of structures. Critical sections are identified along potential corridor routes and then different sensitivity analysis has been applied on these critical sections before final decision is made. Prioritization of alternative routes has been made based on construction cost, operational cost and safety comparisons to identify the most economical and low risk alternative alignment. According to the analysis, from the three alternatives alignments compared, alternative II is economical but alternative III has low risk of construction while alternative I fulfills the required design criteria of the standard better than the other two alignments.
The Fiscal Response To External Aid: A Vector Auto-regressive Analysis (VAR) For Ethiopia

description: The main objective of this study is to access the fiscal response to external aid inflows in Ethiopia, specifically to study the impact of foreign aid inflows on public expenditure, revenue and domestic borrowing in Ethiopia. The paper provides a critical review of literature on the aid-fiscal relation, and then applies a VAR/VECM and impulse response analysis, using data for the period 1961-2007.The study is a good indication that disaggregated data utilization could point out which variables are responsive to changes in external shocks. By studying the particular fiscal dynamics in Ethiopia using three separate models, the study finds that foreign aid in the form of grant and loan has had a positive impact on government expenditure (loan being pro-investment and grant being pro-consumption), both have a negative impact on domestic borrowing (domestic borrowing being more elastic to a change in grant) and indirect tax collection and no effect on the direct one. Moreover, by incorporating total ODA inflow in a separate model, the study tried to analyze the joint impact of budgetary grant and loan, and that of off -budgetary ODA. The results support the conclusion that aid inflows increase public expenditure and are biased to be pro- investment. While total ODA flows have a negative impact on revenue of the government and borrowing from domestic sources, suggesting that aid and domestic borrowing are close substitutes and that higher aid flows displace domestic revenues. In the final analysis to mitigate the undesirable impacts of aid, building a better national capacity to collect domestic revenue and regulatory schemes by donors to avoid possible problems of aid fungiblity should be put in place

description: Deep Ion Beam Lithography (DIBL) has been used for the direct writing of buried graphitic regions in monocrystalline diamond with micrometric resolution. Aiming at the development and the characterization of a fully ion-beam-micromachined solid state ionization chamber, a device with interdigitated electrodes was fabricated by using a 1.8 MeV He+ ion microbeam scanning on a homoepitaxial, grown by chemical vapour deposition (CVD). In order to evaluate the ionizing-radiation-detection performance of the device, charge collection efficiency (CCE) maps were extracted from Ion Beam Induced Charge (IBIC) measurements carried out by probing different arrangements of buried microelectrodes. The analysis of the CCE maps allowed for an exhaustive evaluation of the detector features, in particular the individuation of the different role played by electrons and holes in the formation of the induced charge pulses. Finally, a comparison of the performances of the detector with buried graphitic electrodes with those relevant to conventional metallic surface electrodes evidenced the formation of a dead layer overlying the buried electrodes as a result of the fabrication process.

description: In this work, we describe the charge transport in two-dimensional (2D) Schottky barrier field-effect transistors (SB-FETs) based on the carrier injection at the Schottky contacts. We first develop a numerical model for thermionic and field-emission processes of carrier injection that occur at a Schottky contact. The numerical model is then simplified to yield an analytic equation for current versus voltage ($I$-$V$) in the SB-FET. The lateral electric field at the junction, controlling the carrier injection, is obtained by accurately modeling the electrostatics and the tunneling barrier width. Unlike previous SB-FET models that are valid for near-equilibrium conditions, this model is applicable for a broad bias range as it incorporates the pertinent physics of thermionic, thermionic field-emission, and field-emission processes from a 3D metal into a 2D semiconductor. The $I$-$V$ model is validated against the measurement data of 2-, 3-, and 4-layer ambipolar MoTe$_2$ SB-FETs fabricated in our lab, as well as the published data of unipolar 2D SB-FETs using MoS$_2$. Finally, the model's physics is tested rigorously by comparing model-generated data against TCAD simulation data.
