Acoustic Phonon Characteristics of Gallium Oxide Single Crystals Investigated with Brillouin-Mandelstam Light Scattering Spectroscopy
Dylan Wright, Erick Guzman, Md. Sabbir Hossen Bijoy +5
We report an investigation of the bulk and surface acoustic phonons in gallium oxide ultra-wide bandgap single crystals along various crystallographic directions using Brillouin-Ma…
Acoustic and Optical Phonon Frequencies and Acoustic Phonon Velocities in Silicon-Doped Aluminum Nitride Thin Films
Dylan Wright, Dinusha Herath Mudiyanselage, Erick Guzman +6
We report the results of the study of the acoustic and optical phonons in Si-doped AlN thin films grown by metalorganic chemical vapor deposition on sapphire substrates. The Brillo…
Low-Frequency Electronic Noise in the Aluminum Gallium Oxide Schottky Barrier Diodes
Subhajit Ghosh, Dinusha Herath Mudiyanselage, Sergey Rumyantsev +5
We report on the low-frequency electronic noise in (AlGa)O Schottky barrier diodes. The noise spectral density reveals 1/f dependence, characteristic of the fli…
Effect of crystalline anisotropy on vertical (-201) and (010) beta-Ga2O3 Schottky barrier diodes on EFG single-crystal substrates
Houqiang Fu, Hong Chen, Xuanqi Huang +4
Vertical (-201) and (010) beta-Ga2O3 Schottky barrier diodes (SBDs) were fabricated on single-crystal substrates grown by edge-defined film-fed growth (EFG) method. High resolution…
