A planar force-constant model for phonons in wurtzite GaN and AlN: Application to hexagonal GaN/AlN superlattices

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/28903A planar force-constant model is developed for longitudinal phonons of wurtzite GaN and AlN propagating along the [0001] direction. The proposed model is then applied to the study of the phonon modes in hexagonal GaN/AlN superlattices in the longitudinal polarization. The confinement of the superlattice phonon mode is discussed.10 pages, 4 figures, RevTexSoft Condensed MatterA planar force-constant model for phonons in wurtzite GaN and AlN: Application to hexagonal GaN/AlN superlatticestext
