Abstract

A series of pseudomorphic ZnTe/AlSb/GaSb epilayer/epilayer heterostructures, aimed at the realization of novel wide band-gap light-emitting devices, was grown by molecular beam epitaxy. The structures were evaluated by several techniques including transmission electron microscopy (TEM), x-ray rocking curves, photoluminescence (PL), and Raman spectroscopy. Reflection high-energy electron diffraction intensity oscillations were observed during nucleation of ZnTe. The presence of dislocation-free pseudomorphic structures was confirmed by TEM. The PL spectra of ZnTe epilayers showed dominant near-band-edge features composed of free and shallow impurity bound excitons.
