Specular Reflection of THz Coherent Acoustic Phonons at Solid-Liquid Interfaces

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate significant reductions and spectral oscillations in THz coherent-phonon reflectivity at GaN-water interfaces. Our results indicated that the nanoscaled interfacial structures and water molecular resonances are responsible for the observed specular coupling characteristics.
