Revealing epitaxial relationships at GaO interfaces with p-type oxides
Anna Sacchi, Krishna Acharya, Michelle A. Smeaton +5
p-type oxide contact layers such as CrO and NiO are attracting increasing interest in pn-heterojunctions with n-type monoclinic -GaO for high-power electronic de…
Low resistance NiO/β-Ga_{2}O_{3} heterojunction diodes grown via molecular beam epitaxy
Dagny Sacksteder, Anna Sacchi, Renae Gannon +4
NiO is one of the most important p-type oxide contact materials used in many semiconductor technologies. However, current NiO growth methods can induce interfacial damage that dimi…
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…
Revealing the Atomic Structure of NiO/GaO Interfaces
Michelle A. Smeaton, Krishna Acharya, Anna Sacchi +5
NiO/GaO heterojunctions have garnered significant attention for use in power electronics due to the ultrawide bandgap and wafer-scale availability of GaO an…
Fast Homoepitaxy on (100) \b{eta}-Ga2O3 Substrates with Large Grown-In Offcut
M. Brooks Tellekamp, Drew Haven, David Joyce +7
The choice of crystalline orientation and offcut angle is non-trivial for low-symmetry , where anisotropy impacts bulk and thin film synthesis, material pr…
Composition-dependent Thin-film Synthesis of Layered Ternary Iron Nitrides FeMN2 (M = W, Mo)
