Abstract
Epitaxial layers of ZnSe and ZnS have been grown on GaAs (100) substra tes by low-pressure metal-organic vapor phase epitaxy (MOVPE) and etch ed out from their substrates, The optical qualify of the layers has be en investigated at 2 K by low-intensity reflection, transmission and p hotoluminescence measurements. At high excitation intensities, the nea r-band-edge luminescence has been determined in both ZnS and ZnSe samp les. Exciton and biexciton contributions have been studied.
