Abstract

Time-resolved spectroscopy of the recombining exciton state in a highly strained II-VI semiconductor superlattice CdTe/ZnTe reveals strong localization effects at low lattice temperatures. Such phenomena originate naturally from small deviations in structural perfection on a monolayer scale in a strained superlattice with a small valence band offset. The quasi-2D aspect enhances the localization phenomena further.
