Electrochemical Screening of Contact Layers for Metal Halide Perovskites
Moses Kodur, Zachary Dorfman, Ross A. Kerner +6
Optimizing selective contact layers in photovoltaics is necessary to yield high performing stable devices. However, this has been difficult for perovskites due to their complex int…
Excitons in Bulk and Layered Chromium Tri-Halides: From Frenkel to the Wannier-Mott Limit
Swagata Acharya, Dimitar Pashov, Alexander N. Rudenko +3
Excitons with large binding energies 2-3 eV in CrX are historically characterized as being localized (Frenkel) excitons that emerge from the atomic transitions…
Band gap analysis and carrier localization in cation-disordered ZnGeN
Jacob J. Cordell, Garritt J. Tucker, Adele C. Tamboli +1
Cation site disorder provides a degree of freedom in the growth of ternary nitrides for tuning the technologically relevant properties of a material system. For example, the band g…
Bridging Nano and Micro-scale X-ray Tomography for Battery Research by Leveraging Artificial Intelligence
Jonathan Scharf, Mehdi Chouchane, Donal P. Finegan +11
X-ray Computed Tomography (X-ray CT) is a well-known non-destructive imaging technique where contrast originates from the materials' absorption coefficients. Novel battery characte…
Theoretical insights for Improving the Schottky-barrier Height at the GaO/Pt Interface
Félix Therrien, Andriy Zakutayev, Vladan Stevanović
In this work we study the Schottky barrier height (SBH) at the junction between -GaO and platinum, a system of great importance for the next generation of high-power and…
n-type electrical conduction in SnS thin films
Issei Suzuki, Sakiko Kawanishi, Sage R. Bauers +7
Tin monosulfide (SnS) usually exhibits p-type conduction due to the low formation enthalpy of acceptor-type defects, and as a result n-type SnS thin films have never been obtained.…
Transition metal impurities in Silicon: Computational search for a semiconductor qubit
Cheng-Wei Lee, Meenakshi Singh, Adele Tamboli +1
Semiconductors offer a promising platform for physical implementation of qubits, but their broad adoption is presently hindered by limited scalability and/or very low operating tem…
Combinatorial screening of crystal structure in Ba-Sr-Mn-Ce perovskite oxides with ABO3 stoichiometry
Su Jeong Heo, Andriy Zakutayev
ABO3 oxides with the perovskite-related structures are attracting significant interest due to their promising physical and chemical properties for many applications requiring tunab…
Computational Fermi level engineering and doping-type conversion of Ga2O3 via three-step synthesis process
Anuj Goyal, Andriy Zakutayev, Vladan Stevanović +1
Ga2O3 is being actively explored for high-power and high-temperature electronics, deep-ultraviolet optoelectronics, and other applications. Efficient n-type doping of Ga2O3 has bee…
The Efficacy of the Method of Four Coefficients to Determine Charge Carrier Scattering
Caitlin M. Crawford, Erik A. Bensen, Haley A. Vinton +1
The investigation of the electronic properties of semiconductors is inherently challenging due to the ensemble averaging of fundamentals to transport measurements (i.e., resistivit…
Hot carrier redistribution, electron-phonon interaction, and their role in carrier relaxation in thin film halide perovskites
S. Sourabh, V. R. Whiteside, Y. Zhai +6
Temperature dependent (4K-300K) photoluminescence and transmission spectra are analyzed to study the effect of changing the different components of a perovskite compound, be it A,…
Double-site Substitution of Ce into (Ba, Sr)MnO3 Perovskites for Solar Thermochemical Hydrogen Production
Su Jeong Heo, Michael Sanders, Ryan P. O'Hayre +1
Solar thermochemical hydrogen production (STCH) is a renewable alternative to hydrogen produced using fossil fuels. While serial bulk experimental methods can accurately measure ST…
Optimizing accuracy and efficacy in data-driven materials discovery for the solar production of hydrogen
Yihuang Xiong, Quinn T. Campbell, Julian Fanghanel +25
The production of hydrogen fuels, via water splitting, is of practical relevance for meeting global energy needs and mitigating the environmental consequences of fossil-fuel-based…
Improving Reproducibility of Sputter Deposited Ferroelectric Wurtzite Al0.6Sc0.4N Films using In-situ Optical Emission Spectrometry
Daniel Drury, Keisuke Yazawa, Allison Mis +3
High-Sc Al1-xScxN thin films are of tremendous interest because of their attractive piezoelectric and ferroelectric properties, but overall film quality and reproducibility are wid…
