Raman-scattering study of GaP/InP strained-layer superlattices

Abstract
We discuss the first-order Raman spectra of short-period GaP/InP strained-layer superlattices grown by atomic-layer molecular-beam epitaxy on {001} GaAs substrates. Experimental spectra are successfully explained and compared to the results of simulations consisting of a linear-chain-method calculation combined with the bond-polarizability model.
