Energy Spectrum of Optical Phonons in the Plane Multi-Layer Resonance Tunnel Nanostructure
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 1
Abstract
In the paper, using the dielectric continuum model, we present the investigation of energy spectra of confined and interface optical phonons in the plane multi-layer resonance tunnel nanostructure produced at the base of heterotransitions GaAs/AlAs. We show that the energies of confined optical phonons in this semiconductor nanoheterostructure are determined by the energies of longitudinal polarization vibrations in the respective massive crystals, creating the nanostructure. We observe the dependences of the energies of interface optical phonons on their quasi-momentum and geometrical sizes of GaAs and AlAs nanoshells.
