The extent of interdiffusion in wide band-gap II-VI superlattices, which had been grown at low temperatures, was monitored by measuring the photoluminescence spectra and X-ray diffraction profiles of material which had been annealed at temperatures of between 300 and 550C. It was found that common-ion systems (ZnSe/CdSe) revealed evidence of disordering at temperatures of more than 400 and 450C, respectively. It was concluded that the common-anion binary superlattices were stable against interdiffusion at low growth temperatures.
