Abstract

Thermal degradation of InP single crystal substrates prior to LPE growth has been virtually eliminated by using an improved protection technique. The phosphorus partial pressure provided by a Sn-In-P solution localized inside an external chamber surrounding the InP substrate prior to growth prevents thermal damage to the surface. Nomarski contrast photomicrographs,photoluminescence and X-ray diffractometric measurements indicate that InP substrates protected by this method suffer negligible deterioration, in contrast to the results of the more commonly used cover wafer method.
