The difficulty in achieving the amphoteric doping of wide gap II-VI semiconductors for use in light emitting devices suggests the merits of heterojunction injection. This paper discusses the first epilayer/epilayer ZnTe/AlSb/GaSb heterojunctions grown by MBE. Pseudomorphic ZnTe layers were nucleated on pseudomorphic AlSb layers; the AlSb was grown on homoepitaxial GaSb buffer layers. Free exciton related features were observed in the photoluminescence of ZnTe; dominant features of the PL corresponded to near band-edge transitions. Microstructural quality was examined using TEM and X-ray rocking curves. Cross-sectional TEM images reveal atomically flat interfaces. X-ray rocking curve full width at half maximum values were close to the theoretically expected broadening due to the finite layer thickness.
