Abstract
Raman scattering measurements have been made to determine the elastic deformation in ZnTe-ZnSe strained-layer superlattices grown by hotwall epitaxy. Both ZnSe- and ZnTe-like modes have been observed, which confirms the formation of a superlattice in the multilayer system having a large lattice mismatch between host layers. We observe that the frequencies of the ZnSe-like longitudinal and transverse phonon modes vary strikingly with the relative thickness of ZnTe and ZnSe layers. This effect is fully accounted for by uniform misfit strains which accommodate the lattice mismatch of the host.Keywords
