Computer modeling of Raman spectra of AIIIBV superlattices
Pankin D. V.

	The main aim of this work was to investigate composition and structure dependencies of Raman spectra of AIIIBV nitride-based superlattices. Phonon frequencies and Raman intensities for the short-period and long-period AlN/GaN superlattices were simulated in the framework of dielectric continuum model. The main conclusion is that both the superlattice period and relative thickness of layers could be characterized by Raman lines related to the interface and quasiconfined polar phonon modes.
