ZnSe films have been grown on (100) oriented GaAs substrates by atomic layer epitaxy (ALE) using ZnCl2 and H2Se as source materials. The growth has been performed by using a hydride vapor phase epitaxial growth system. The epilayer thickness was examined for different growth conditions and was found to depend only on the number of substrate rotation cycles for the growth temperature near 450°C. Pseudomorphic ZnSe films on GaAs substrates were achieved by ALE for the growth of 1000 operating cycles. These films show good surface morphology and good crystallographic properties.
