High-Temperature Hydrogen Sensors Based on Gallium Oxide Heterojunction Diodes
William A. Callahan, Kingsley Egbo, Anna Sacchi +5
Long-term, high temperature operation of Ga2O3 devices is a crucial hurdle that must be overcome before widespread adoption of the technology can be achieved, but is largely absent…
Epitaxial growth and semiconductor properties of NiGa2O4 spinel for Ga2O3/NiO interfaces
Kingsley Egbo, Emily M. Garrity, Shivashree Shivamade Gowda +8
Unintentionally formed interfacial layers are ubiquitous in semiconductor devices that operate at extreme conditions. However, these layers' structure and properties often remain u…
Stability, growth, and doping of In(Si, Ge)O as promising n-type wide-gap semiconductors
Cheng-Wei Lee, Kingsley Egbo, Emily Garrity +4
In this paper we investigate, computationally and experimentally, the phase stability, electronic structure properties, and the propensity for n-type doping of InXO$_{7…
Combinatorial synthesis and characterization of thin film Al1-xRExN (RE = Pr3+, Tb3+) heterostructural alloys
Binod Paudel, John S. Mangum, Christopher L. Rom +8
The potential impact of cation-substituted AlN-based materials, such as Al1-xScxN, Al1-xGaxN, and Al1-xBxN, with exceptional electronic, electromechanical, and dielectric propertie…
From Text to Test: AI-Generated Control Software for Materials Science Instruments
Davi M Fébba, Kingsley Egbo, William A. Callahan +1
Large language models (LLMs) are transforming the landscape of chemistry and materials science. Recent examples of LLM-accelerated experimental research include virtual assistants…
Reliable operation of CrO:Mg/ -GaO p-n heterojunction diodes at 600C
William A. Callahan, Kingsley Egbo, Cheng-Wei Lee +3
-GaO-based semiconductor heterojunctions have recently demonstrated improved performance at high voltages and elevated temperatures and are thus promising for applicatio…
Rapid screening of molecular beam epitaxy conditions for monoclinic (InxGa1-x)2O3 alloys
Stephen Schaefer, Davi Febba, Kingsley Egbo +3
Molecular beam epitaxy is one of the highest quality growth methods, capable of achieving theoretical material property limits and unprecedented device performance. However, such u…
