Angle-Resolved Cryogenic Brillouin-Mandelstam Spectroscopy of Surface and Bulk Acoustic Phonons in Diamond
Jordan Teeter, Dylan Wright, Nidhish Thiruthukkal Puthenveettil +2
We used angle-resolved Brillouin-Mandelstam light-scattering spectroscopy to monitor surface and bulk acoustic phonons in diamond along the <100> and <110> crystallographic directi…
Anomalous spin-lattice coupling in a 2D antiferromagnetic semiconductor revealed by surface acoustic Rayleigh waves
Zahra Ebrahim Nataj, Md. Sabbir Hossen Bijoy, Vladislav Korostelev +5
Magnetic order in van der Waals magnets can strongly influence their lattice dynamics, yet how this interaction manifests across different phonon length scales remains unclear. Opt…
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…
