Interface optical phonon modes in wurtzite quantum heterostructures

Abstract

Surface and interface phonon polariton characteristics of wurtzite ZnO/GaN heterostructure Appl. Phys. Lett. 98, 241909 (2011); 10.1063/1.3599715The lifetime of optical phonons in a single heterostructure Simple analytical expressions are derived, herein, for the interface phonon modes of complex SiCand GaN-based substrates. These analytical results are essential for studies of remote polar-optical phonon phenomena in a variety of structures including heterostructures, in two-dimensional (2D) structures such and graphene, BN, and MoS 2 on polar substrates, as well as in efforts to control the bandgaps of such 2D structures through interactions with polar substrates.
