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…
Acoustic and Optical Phonons in Quasi-Two-Dimensional MPX3 Van der Waals Semiconductors
Dylan Wright, Zahra Ebrahim Nataj, Erick Guzman +4
We report the results of the investigation of the acoustic and optical phonons in quasi-two-dimensional antiferromagnetic semiconductors of the transition metal phosphorus trisulfi…
Optical and Acoustic Phonons in Turbostratic and Cubic Boron Nitride Thin Films on Diamond Substrates
Erick Guzman, Fariborz Kargar, Avani Patel +6
We report an investigation of the bulk optical, bulk acoustic, and surface acoustic phonons in thin films of turbostratic boron nitride (t-BN) and cubic boron nitride (c-BN) grown…
The Effects of Boron Doping on the Bulk and Surface Acoustic Phonons in Single-Crystal Diamond
Erick Guzman, Fariborz Kargar, Frank Angeles +7
We report the results of the investigation of bulk and surface acoustic phonons in the undoped and boron-doped single-crystal diamond films using the Brillouin-Mandelstam light sca…
