Abstract
A giant blue shift (approximate to 0.5 eV) and a large decrease in the emission time of a spectral band corresponding to radiative recombina tion of spatially separated electrons and holes are observed in ZnSe/B eTe superlattices at high laser excitation levels. On the basis of num erical calculations, the observed defects are attributed to band bendi ng arising in type-II structures at high carrier density. (C) 1997 Ame rican Institute of Physics.
