Photovoltage spectroscopy and electroluminescence of ZnSe/Cd/sub x/Zn/sub 1-x/Se superlattices
The ZnSe/Cd/sub x/Zn/sub 1-x/Se superlattices with non-doping layers, grown by molecular beam epitaxy, were investigated by electroluminescence and photovoltage spectroscopy. Green-blue electroluminescence from the quantum wells has been observed at 77 K and 293 K. Well-resolved peaks attributed to excitonic absorption, as well as photosensitivity bands corresponding to the Cd/sub x/Zn/sub 1-x/Se/ZnSe superlattice region and the ZnSe buffer layer, have been observed in photovoltaic measurements.
