description: The CP Violating asymmetry in Bs mixing (beta_s) is one of the most promising measurements where physics beyond the Standard Model could be revealed. As such, analyses need to be subjected to great scrutiny. The mode Bs -> J/psiϕhas been used, and the mode Bs -> ϕϕproposed for future measurements. These modes both have two vector particles in the final state and thus angular analyses must be used to disentangle the contributions from CP+ and CP- configurations. The angular distributions, however, could be distorted by the presence of S-waves masquerading as low mass K+K- pairs, that could result in erroneous values of beta_s. The S-waves could well be the result of a final state formed from an s-quark anti-s-quark pair in a 0+ spin-parity state, such as the f0(980) meson. Data driven and theoretical estimates of the Bs decay rate into the CP+ final state J/psi f0(980) are given, when f0 -> pi+pi-. The S-wave contribution in Jψϕshould be taken into account when determining beta_s by including a K+K- S-wave amplitude in the fit. This may change the central value of current results and will also increase the statistical uncertainty. Importantly, the J/psi f0(980) mode has been suggested as an alternative channel for measuring beta_s.

title: Establishment and characterisation of USP29 as a novel regulator of Hypoxia Inducible Factor α
Creators: name: Schober, A
Publisher: name: University of Liverpool Repository
Year: 2017

description: The hypoxia signalling pathway controls the adaptation of cells to decreased oxygen availability. When oxygen becomes limiting, the central transcription factor of the pathway, hypoxia-inducible factor (HIF), is activated and induces the expression of a set of genes, which cause a glycolytic switch, enhance cell survival and induce angiogenesis. While those are necessary physiological adaptive processes, they are also hallmarks of cancer and hypoxia signalling is often found activated in cancer. However, current knowledge about the regulation of the hypoxia signalling pathway is not able to satisfactorily explain the deregulation found in cancer. Therefore, the aim of this work was to discover new regulatory mechanisms that could be responsible for sustained hypoxia signalling and therefore might represent future therapeutic targets. We focused on how post-translational modifications affected the properties of the central proteins of the pathway. Using standard biochemical approaches and fluorescence lifetime imaging, we found that the ubiquitin specific protease 29 (USP29) is a deubiquitinase for HIF-1α. Moreover, USP29 is the first ubiquitin protease towards HIF-2α. USP29 de-conjugates poly-ubiquitin from HIF-α and prevents its proteasomal degradation, leading to its stabilisation even in normoxic conditions. Importantly, this action of USP29, while dependent on its catalytic activity, was not dependent on the classical prolyl-hydroxylation and pVHL-mediated ubiquitination, and therefore we propose that USP29 is a non-canonical HIF activator. As hardly any reports about USP29 were available, we next aimed to characterise this maternally imprinted protein. We found that USP29 itself was subject to poly-ubiquitin-mediated destabilisation, but was able to remove the ubiquitination itself and therefore auto-stabilise in a catalytic activity-dependent way. Furthermore, we demonstrated that USP29 formed homodimers in living cells. Finally, we found that USP29 mRNA levels correlated with disease progression and severity in prostate cancer and suggest that USP29 might become an attractive target for therapeutic targeting of hypoxia signalling in the future.
Coherence and Correlation Effects in Coupled Quantum Dot Systems

description: Coherence and correlations between electrons in weakly coupled quantum dots are considered in general nonequilibrium situations. The influence of strong onsite Coulomb interaction on the evolution of the density matrix of a system of coherently coupled quantum dots and on the coherence of the transport is investigated. It turns out, that spin entanglement between electrons on spatially separated quantum dots can be induced in nonequilibrium. We study in detail the precursors of this phenomenon.
Expiratory time constant heterogeneity in experimental acute respiratory distress syndrome
Creators: name: Henderson, William Roy
Publisher: name: University of British Columbia
Year: 2016

description: Purpose This thesis evaluated regional heterogeneity of pulmonary mechanical values within models of lung injury. To this end four separate studies were completed. I evaluated regional expiratory time constant (τE) heterogeneity and tissue strain (ε) in a lung model using functional respiratory imaging (FRI) (Study 1, Chapter 2), and developed an in vivo porcine model of lung injury (Study 2, Chapter 3). This model was used to assess changes in τE due to manipulations of respiratory gas density (Study 3, Chapter 4) and mechanical ventilation parameters (Study 4, Chapter 5). Methods Study 1: Using computerized tomography (CT) images we generated 3-dimensional lung models. These were used calculated global and regional values for resistance, elastance, ε and τE under three different airway pressure conditions. Study 2: Experimental lung injury was induced in 11female Yorkshire X pigs. Necropsy, light and electron microscopy of lung was performed. Study 3: I utilized a multi-compartment model to describe the effects of changes in tidal volume (VT) and positive end-expiratory pressure (PEEP) on lung emptying during passive deflation before and after experimental lung injury in 6 adult female Yorkshire X pigs. Expiratory time constants (τE) were determined by partitioning the expiratory flow-volume (V˙ V) curve into multiple discrete segments. Study 4: Tracheal pressure and flow were measured in 7 pigs before and after experimental lung injury. Gas density was altered by using helium-oxygen (He), sulfur hexafluoride-oxygen (SF6) and nitrogen-oxygen (N2) gas. Conclusions Functional respiratory imaging demonstrates regional variation in both ε and τE. These findings raise questions about the use of whole lung measures of ε and τE to guide clinical management of lung injury (Study 1). I developed a stable model of lung injury using SPA that replicates the light and electron microscopic findings seen in human ARDS (Study 2). A pragmatic strategy using changes in the pattern of expiration described by a multi-compartment model of τE reveals that alterations in and gas density (Study 3) as well as PEEP and VT (Study 4) change expiratory pulmonary mechanics. These observations lay the groundwork for future clinical studies in lung injured patients.

description: In recent years higher-dimensional black holes have attracted much interest because of various developments in gravity and high energy physics. But whereas higher-dimensional charged static (Tangherlini) and uncharged rotating (Myers-Perry) black holes were found long ago, black hole solutions of Einstein-Maxwell theory, are not yet known in closed form in more than 4 dimensions, when both electric charge and rotation are present. Here we therefore study these solutions and those of Einstein-Maxwell-dilaton theory, by using numerical and perturbative methods, and by exploiting the existence of spacetime symmetries. The properties of these black holes reveal new interesting features, not seen in D=4. For instance, unlike the D=4 Kerr-Newman solution, they possess a non-constant gyromagnetic factor.

title: Evaluation of Horizontal Gene Transfer Between Genetically Engineered Cyanobacteria and Gram-Negative Bacteria

Year: 2021

description: As the world population is increasing and societies become more technology driven, there is an imperative to develop ‘green energy’ sources to protect our planet. Cyanobacteria that have been genetically engineered to produce organic compounds that may be burnt as fuels show great potential, as they are an environmentally friendly and self-renewable, net carbon-neutral option. However, there are potential risks in the development and use of genetically modified organisms (GMOs). We need to understand in advance the risks that GMOs may pose to our environment and to animal and human health. This will enable experimental procedures, containment strategies and policies to be developed to prevent accidents and eliminate potential harmful effects of GMOs in the environment such as sharing antibiotic genes to native microorganisms. My research seeks to assess the bio-risk posed by engineered cyanobacteria and their capability of transferring genes of antibiotic resistance to other bacteria, they may encounter in their environment outside of laboratory conditions. Here genetically engineered (GE) cyanobacteria that contain antibiotic resistance genes commonly used as selective markers, are being studied and their ability to horizontally transfer to wild-type bacterial strains. In aim one, the plasmid vector that carries the transgenes to confer antibiotic resistance and to theoretically produce biofuel was introduced into the cyanobacteria, Thermosynechococcus elongatus BP1 and select other gram-negative bacterial strains, Escherichia coli K12, Escherichia coli DH5α, and Pseudomonas putida KT2440, to assess their ability to carry the plasmid and obtain antibiotic resistance. In the second aim, the ability for the plasmid to undergo horizontal gene transfer (HGT), from GE cyanobacteria to two different strains of E. coli was determined. In the third aim, the ability of P. putida KT2440 to uptake the plasmid via HGT from GE cyanobacteria was studied. This research also examines the fundamental mechanisms of horizontal gene transfer, which is foundational to microbial life and not completely understood. The results reveal that HGT occurs between our model cyanobacteria and E. coli strains but not Pseudomonas. This research provides foundational knowledge to help develop policies and safeguards for the safe design and use of GMOs.

description: Adjacent members like trapezoidal sheeting or sandwich panels can reduce the problem of lateral torsional buckling of beams by providing stabilization either by shear stiffness or by torsional restraint. Both types are investigated in this thesis by tests and numerical calculations. This concerns the shear stiffness of steel sheeting diaphragms with only two edges fastened against lateral displacements of the beam compression chord and the torsional restraint of the rotation by sandwich panels.

description: Exact bolometric light curves of supernova shock breakouts are derived based on the universal, non relativistic, planar breakout solutions (Sapir et al. 2011), assuming spherical symmetry, constant Thomson scattering opacity, κ, and angular intensity corresponding to the steady state planar limit. These approximations are accurate for progenitors with a scale height much smaller than the radius. The light curves are insensitive to the density profile and are determined by the progenitor radius R, and the breakout velocity and density, v_0 and ρ_0 respectively, and κ. The total breakout energy, E_BO, and the maximal ejecta velocity, v_max, are shown to be E_BO=8.0πR^2κ^-1cv_0 and v_max=2.0v_0 respectively, to an accuracy of about 10%. The calculated light curves are valid up to the time of transition to spherical expansion, t_sph\approx R/4v_0. Approximate analytic expressions for the light curves are provided for breakouts in which the shock crossing time at breakout, t_0=c/κρ_0v_0^2, is << R/c (valid for R<10^14 cm). Modifications of the flux angular intensity distribution and differences in shock arrival times to the surface, Δt_asym, due to moderately asymmetric explosions, affect the early light curve but do not affect v_max and E_BO.

description: We propose an original test of Lorentz invariance in the interaction between a particle spin and an electromagnetic field and report on a first measurement using ultracold neutrons. We used a high sensitivity neutron electric dipole moment (nEDM) spectrometer and searched for a direction dependence of a nEDM signal leading to a modulation of its magnitude at periods of 12 and 24 hours. We constrain such a modulation to $d_{12} < 15 \times 10^{-25} \ e\,{\rm cm}$ and $d_{24} < 10 \times 10^{-25} \ e\,{\rm cm}$ at 95~\% C.L. The result translates into a limit on the energy scale for this type of Lorentz violation effect at the level of ${\cal E}_{LV} > 10^{10}$~GeV.

title: The Involvement of Receptor Interacting Protein Kinase 1 (RIPK1) in the Pathogenesis of Acute Pancreatitis
Creators: name: Ouyang, Y
Publisher: name: University of Liverpool Repository
Year: 2017

description: Acute pancreatitis (AP) is a severe and potentially fatal human disease characterized by parenchymal necrosis with associated inflammation. Necroptosis is a form of controlled necrosis which is mediated through receptor interacting protein kinase 1 (RIPK1), RIPK3 and mixed lineage kinase domain-like protein (MLKL) as a regulated cell death pathway. Accumulating studies have demonstrated that necroptosis plays an important role in the pathogenesis of AP related to RIPK3 and MLKL. However, the function of RIPK1 in the pancreas, especially under pathological conditions, has remained unclear. The aims of this study were to investigate the effects of RIPK1 kinase activity, using gene modification and pharmacological inhibition, on in vitro cell death, reactive oxygen species (ROS) production, and Ca2+ signalling and in vivo using three experimental AP models, to further understand the role of RIPK1 in AP. Both genetic modification and pharmacological inhibition led to significant reductions of acinar cell necrosis. In addition, chemical inhibitors were also found to reduce TLCS-induced apoptosis, ROS production and CCK-induced sustained Ca2+ elevations. The severity of experimental pancreatitis in TLCS- , FAEE- and CER-AP was only partially protected in Ripk1K45A mice compared to strain-matched controls. Application of Nec-1 (56 mg/kg) through a mini pump as a treatment markedly reduced the severity of AP in all three experimental models. In addition, inhibition of indoleamine 2, 3-dioxygenase (IDO), another reported target of Nec-1, caused partial protection in TLCS-AP. In conclusion, RIPK1 kinase activity may play a role in the pathogenesis of AP, however, the results indicated that it would not be an appropriate target for drug development. In contrast, Nec-1 significantly ameliorated AP in all experimental models tested, likely through multiple pathways, suggesting further elucidation of its effects might assist the development of novel therapies.

description: Charge transport in GaN quantum well (QW) devices grown in non-polar direction has been theoretically investigated . Emergence of anisotropic line charge scattering mechanism originating as a result of anisotropic rough surface morphology in conjunction with in-plane built-in polarization has been proposed. It has shown that in-plane growth anisotropy leads to large anisotropic carrier transport at low temperatures. At high temperatures, this anisotropy in charge transport is partially washed out by strong isotropic optical phonon scattering in GaN QW.

description: We show that the quantum statistical mechanics describing quantum and thermal properties of objects has only the sense of a particular semiclassical approximation. We propose a more general (than that theory) microdescription of objects in a heat bath taking a vacuum into account as an object environment; we call it $(\hbar,k)-$dynamics ($\hbar kD)$. We introduce a new generative operator, a Schrödingerian or a stochastic action operator, and will show its fundamental role in the determination of such macroquantities as internal energy, effective temperature, and effective entropy. We establish that $\hbar kD$ can serve as an initial microtheory for constructing a modified thermodynamics. On this ground, we can explain the universality of the ratio "effective action to effective entropy" at zero temperature and its minimal value in the form $\hbar/2k$. This result corresponds to experimental data obtained recently under studying a new matter state - a nearly perfect fluid.

description: Reactive chlorine species (RCS) like sodium hypochlorite (NaOCl) are potent oxidizing agents and widely used biocides in surface disinfection, water treatment, and biofilm elimination. Moreover, RCS are also produced by the human immune system to kill invading pathogens. However, bacteria have developed mechanisms to survive the damage caused by RCS. Using the comprehensive Pseudomonas aeruginosa PA14 transposon mutant library in a genetic screen, we identified a total of 28 P. aeruginosa PA14 mutants whose biofilms showed increased susceptibility to NaOCl in comparison to PA14 WT biofilms. Of these, ten PA14 mutants with a disrupted apaH, PA0793, acsA, PA1506, PA1547, PA3728, yajC, queA, PA3869, or PA14_32840 gene presented a 4-fold increase in NaOCl susceptibility compared to wild-type biofilms. While none of these mutants showed a defect in biofilm formation or attenuated susceptibility of biofilms toward the oxidant hydrogen peroxide (H2O2), all but PA14_32840 also exhibited a 2–4-fold increase in susceptibility toward the antibiotic ciprofloxacin. Further analyses revealed attenuated levels of intracellular ROS and catalase activity only for the apaH and PA1547 mutant, providing insights into the oxidative stress response in P. aeruginosa biofilms. The findings of this paper highlight the complexity of biofilm resistance and the intricate interplay between different mechanisms to survive oxidative stress. Understanding resistance strategies adopted by biofilms is crucial for developing more effective ways to fight resistant bacteria, ultimately contributing to better management of bacterial growth and resistance in clinical and environmental settings.

description: High Energy Physics data sets are often characterized by a huge number of events. Therefore, it is extremely important to use statistical packages able to efficiently analyze these unprecedented amounts of data. We compare the performance of the statistical packages StatPatternRecognition (SPR) and Toolkit for MultiVariate Analysis (TMVA). We focus on how CPU time and memory usage of the learning process scale versus data set size. As classifiers, we consider Random Forests, Boosted Decision Trees and Neural Networks. For our tests, we employ a data set widely used in the machine learning community, "Threenorm" data set, as well as data tailored for testing various edge cases. For each data set, we constantly increase its size and check CPU time and memory needed to build the classifiers implemented in SPR and TMVA. We show that SPR is often significantly faster and consumes significantly less memory. For example, the SPR implementation of Random Forest is by an order of magnitude faster and consumes an order of magnitude less memory than TMVA on Threenorm data.

The cumulative effects of physiology, temperature, and natal water cues on the migration behaviour and survival of adult sockeye salmon during passage through the Seton River hydroelectric system, British Columbia
Creators: name: Middleton, Collin Thomas
Publisher: name: University of British Columbia
Year: 2016

description: Upriver migrating adult Pacific salmon home to natal sites following natal water cues while also undergoing a suite of physiological changes to prepare for spawning. Migrants can encounter myriad environmental conditions that are physiologically and energetically challenging throughout these journeys. Many freshwater migration corridors have also been converted into hydroelectric systems (hydrosystems) that can change the composition of flows such that the availability and concentration of natal water cues can vary substantially. How such flow composition changes affect migration behaviour has rarely been examined, while the cumulative effects of environmental and physiological factors on the fate of migrating adult salmon in regulated rivers are not well understood. Using the Seton hydrosystem in British Columbia and two populations of sockeye salmon as a model, I conducted a field radio-tagging study that examined how physiology, temperature, and natal water concentration affected the behaviour and fate of adult salmon migrating through a regulated river while enroute to natal spawning sites. Most tagged migrants (89%) delayed in the outlet of the Seton powerhouse that discharges strong concentrations of natal water, and subsequently wandered in the mainstem Fraser River before continuing their upstream migration into the Seton River, where natal water cues can also vary. I found few associations between physiological stress and reproductive hormone levels with powerhouse delays and wandering, although fish with higher energy content were generally slower migrating through the whole hydrosystem. Higher temperatures and elevated natal water concentrations were associated with shorter delays at the powerhouse and less wandering, but only among late-run migrants. I found little evidence that the cumulative effects of physiology and environmental conditions during hydrosystem passage were related to survival to natal sites, suggesting that other factors aside from those encountered during hydrosystem passage (e.g. environmental factors prior to reaching the hydrosystem) may have played a role in influencing survival post dam-passage. My thesis provides the first detailed account of how varying natal water concentrations affects the homing behaviour of wild migrating adult salmon and how the cumulative effects of physiology and environmental conditions experienced during passage through a regulated migration corridor influences survival to natal sites.

description: Hf silicate films (HfO_2)_{0.25}(SiO_2)_{0.75} with thicknesses in the range 4-20 nm were grown on silicon substrate by atomic layer deposition at 350 deg.C.The Hf distributions in as-grown and 800 deg.C annealed films were investigated by high resolution transmission electron microscopy (HRTEM), angle-resolved x-ray photoelectron spectroscopy (ARXPS) and medium energy ion scattering (MEIS). HRTEM images show a layered structure in films thinner than 8 nm. The ARXPS data also reveal a non-uniform distribution of Hf throughout the film depth. Diffusion of SiO_2 to the film surface after a longer time anneal was observed by MEIS. All these observations provide evidence for surface-directed spinodal decomposition in the pseudobinary (HfO_2)_x(SiO_2)_{1-x} alloy system.

description: Low energy excitation of surface states of a three-dimensional topological insulator (3DTI) can be described by Dirac fermions. By using a tight-binding model, the transport properties of the surface states in a uniform magnetic field is investigated. It is found that chiral surface states parallel to the magnetic field are responsible to the quantized Hall (QH) conductance $(2n+1)\frac{e^2}{h}$ multiplied by the number of Dirac cones. Due to the two-dimension (2D) nature of the surface states, the robustness of the QH conductance against impurity scattering is determined by the oddness and evenness of the Dirac cone number. An experimental setup for transport measurement is proposed.

description: In this paper we analyze a constant multiple-input multiple-output interference channel where a set of active users are cooperating through interference alignment while a set of secondary users desire access to the channel. We derive the minimum number of secondary transmit antennas required so that a secondary user can use the channel without affecting the sum rate of the active users, under a zero-forcing equalization assumption. When the secondary users have enough antennas, we derive several secondary user precoders that approximately maximize the secondary users' sum rate without changing the sum rate of the active users. When the secondary users do not have enough antennas, we perform numerical optimization to find secondary user precoders that cause minimum degradation to the sum rate of the active users. Through simulations, we confirm that i) with enough antennas at the secondary users, gains equivalent to the case of all the users cooperating through interference alignment is obtainable, and ii) when the secondary users do not have enough antennas, large rate losses at the active users can be avoided.

description: The emission-line Be star HD 215227 lies within the positional error circle of the newly identified gamma-ray source AGL J2241+4454. We present new blue spectra of the star, and we point out the morphological and variability similarities to other Be binaries. An analysis of the available optical photometry indicates a variation with a period of 60.37 +/- 0.04 d, which may correspond to an orbital modulation of the flux from the disk surrounding the Be star. The distance to the star of 2.6 kpc and its relatively large Galactic latitude suggest that the binary was ejected from the plane by a supernova explosion that created the neutron star or black hole companion. The binary and runaway properties of HD 215227 make it an attractive candidate as the optical counterpart of AGL J2241+4454 and as a new member of the small class of gamma-ray emitting binaries.

title: Atomic layer deposition zinc oxide devices for transparent electronics

description: Zinc oxide (ZnO) films deposited using atomic layer deposition (ALD) and plasma enhanced (PE)-ALD for transparent electronics have been explored in this thesis by characterising the films electrically and physically. Thin-film transistors (TFTs) and Schottky diodes have been successfully demonstrated using ALD based thin-films as active layers. The challenge of reducing the intrinsically high conductivity is addressed through two approaches namely the use of substitutional dopants via ALD and tuning of the plasma conditions during PEALD deposition. Initial characterisation established that using Mg as a substitutional alloy, reduced the films conductivity. TFTs were fabricated using lithography, on highly doped Si wafers with thermally grown SiO2 as the gate oxide. The effect of using Mg was to reduce the off-current by a factor of 105. An optimum ratio between the Mg and Zn precursor of 12.5 % was established, defined by a maximum saturation mobility (μsat) of 4 cm2/Vs. In addition, the band gap of the Mg doped ZnO film increased from 3.3 eV to 3.44 eV, through the formation of MgO states within the film. The first instance of Nb doped ZnO for TFTs applications are reported in this thesis. TFTs were fabricated in the same manner as for Mg doped ZnO, however, a capping layer of 5 nm of Al2O3 prior to NbZnO deposition was required to mitigate gate oxide leakage and improve the interface quality. Optimal characteristics were achieved with a lower ratio of 3.8 % between the Nb and Zn precursor. A maximum μsat of 8 cm2/Vs was achieved. The higher mobility and lower precursor percentages for Nb originate from the higher oxidation state of the dopant. A lower sub-threshold swing of 220 mV/dec was achieved for Nb doped films compared to 900 mV/dec for Mg doped films, supporting the advantage of using Nb to control the conductivity of ZnO ALD thin-films for TFT applications. In addition, the sub-band gap states in ZnO film was modelled from current-voltage and capacitance-voltage measurements, where good correlation between both techniques was achieved. Optimisation of PEALD ZnO for Schottky diode applications was established with a deposition temperature of 80 oC and plasma time of 50 s. The use of oxidised metals for the Schottky contact, namely AgxO and Pt¬O¬x was required to obtain good Schottky parameters. These contact metals aim to mitigate the oxygen deficiencies at surface of ZnO. Relatively low ideality factors of < 1.4 are achieved using both Schottky contacts. Thermionic emission was established as the dominant conduction mechanism. The relatively large ideality factors are thought to originate from the polycrystalline nature of the ZnO film.

description: We consider a fully-connected network of leaky integrate-and-fire neurons with spike-timing-dependent plasticity. The plasticity is controlled by a parameter representing the expected weight of a synapse between neurons that are firing randomly with the same mean frequency. For low values of the plasticity parameter, the activities of the system are dominated by noise, while large values of the plasticity parameter lead to self-sustaining activity in the network. We perform event-driven simulations on finite-size networks with up to 128 neurons to find the stationary synaptic weight conformations for different values of the plasticity parameter. In both the low and high activity regimes, the synaptic weights are narrowly distributed around the plasticity parameter value consistent with the predictions of mean-field theory. However, the distribution broadens in the transition region between the two regimes, representing emergent network structures. Using a pseudophysical approach for visualization, we show that the emergent structures are of "path" or "hub" type, observed at different values of the plasticity parameter in the transition region.

description: The impact of Flavin adenine dinucleotide (FAD) on sulfate-reducing bacteria (SRB) corrosion of a pipeline welded joint (WJ) was investigated under anaerobic condition in this paper. The results showed that the thickness of the corrosion product on heat affected zone (HAZ) was lower than that on base metal (BM) and welded zone (WZ), and the FAD addition enhanced the development of the protruding microbial tubercles on the WJ. The local corrosion degrees of the BM and WZ coupons were significantly higher than that of the HAZ coupon. Besides, the FAD addition simultaneously promoted local corrosion of all three zones of the WJ in the SRB inoculated environment, and the promotion role was much more pronounced on the WZ coupons. The selective promotion effect of FAD on SRB corrosion in the WJ was attributed to the special structure of the WZ, the selected SRB attachment and the FAD/FADH2 redox feedback cycle.

description: Hybrid field effect transistors based on the organic polymer poly(3-hexylthiophene) (P3HT) and inorganic zinc oxide were investigated. In this report we present one of the first studies on hybrid transistors employing one polymeric transport layer. The sol-gel processed ZnO was modified via Al doping between 0.8 and 10 at.%, which allows a systematic variation of the zinc oxide properties, i.e. electron mobility and morphology. With increasing doping level we observe on the one hand a decrease of the electron mobilities by two orders of magnitude,on the other hand doping enforces a morphological change of the zinc oxide layer which enables the infiltration of P3HT into the inorganic matrix. X-ray reflectivity (XRR) measurements confirm this significant change in the interface morphology for the various doping levels. We demonstrate that doping of ZnO is a tool to adjust the charge transport in ZnO/P3HT hybrids, using one single injecting metal (Au bottom contact) on a SiO2 dielectric. We observe an influence of the zinc oxide layer on the hole mobility in P3HT which we can modify via Al doping of ZnO. Hence, maximum hole mobility of 5e-4 cm^2/Vs in the hybrid system with 2 at.% Al doping. 5 at.% Al doping leads to a balanced mobility in the organic/inorganic hybrid system but also to a small on/off ratio due to high off-currents.
