Phonons in Short-Period GaN/AlN Superlattices: Group-Theoretical Analysis, <em>Ab initio</em> Calculations, and Raman Spectra

Phonons in Short-Period GaN/AlN Superlattices: Group-Theoretical Analysis, <em>Ab initio</em> Calculations, and Raman Spectra

We report the results of experimental and theoretical studies of phonon modes in GaN/AlN superlattices (SLs) with a period of several atomic layers, grown by submonolayer digital plasma-assisted molecular-beam epitaxy, which have a great potential for use in quantum and stress engineering. Using det...
