Laser-Ablated Au Electrodes with Preferred Orientation and Flat Interface on Oxides
Ambrose Seo, Richard Lai, Sujan Shrestha +5
Gold (Au) thin-film electrodes deposited on oxides by pulsed laser deposition (PLD) exhibit distinctive structural properties compared with thermally evaporated Au films. While the…
Coordination-Sensitive Nanoscale Analysis of Defect-Driven Phase Transformation in Si-Doped (AlXGa1-X)2O3
Shaon Das, Jith Sarker, Christopher Chae +5
Defect-driven phase instability critically influences the structural reliability of ultrawide bandgap oxides, yet direct nanoscale metrics linking local chemistry to structural tra…
Broad-Range Tuning of Ferroelectric Switching of LaxBi1-xFeO3 Epitaxial Films via Digital Doping using Off-Axis Co-Sputtering
Katelyn Lazareno, Christopher Chae, Becky Haight +7
To investigate the scope of ferroelectric behavior in La-substituted BiFeO3 films, LaxBi1-xFeO3 epitaxial films were synthesized using off-axis co-sputtering on SrTiO3(001) and DyS…
Optimizing Metal-Organic Chemical Vapor Deposition for Ultrawide Band-Gap MgSiN2 Thin Films
Chenxi Hu, Abdul Mukit, Vijay Gopal Thirupakuzi Vangipuram +4
Orthorhombic II-IV nitride semiconductors offer an expanded and more tunable material set with unique properties, while maintaining close compatibility with the wurtzite crystal st…
Metalorganic Chemical Vapor Deposition of \b{eta}-(AlxGa1-x)2O3 thin films on (001) \b{eta}-Ga2O3 substrates
A. F. M. Anhar Uddin Bhuiyan, Lingyu Meng, Hsien-Lien Huang +5
Phase pure \b{eta}-(AlxGa1-x)2O3 thin films are grown on (001) oriented \b{eta}-Ga2O3 substrates via metalorganic chemical vapor deposition (MOCVD). By systematically tuning the pr…
