METHOD OF THERMALLY TREATING ZNSE CRYSTAL SUBSTRATE, THERMALLY TREATED SUBSTRATE, AND LIGHT EMITTING DEVICE

摘要

This invention relates to a method for the heat treatment of a ZnSe crystal substrate to dope it with Al as a donor impurity, a ZnSe crystal substrate prepared by this heat treatment and a light-emitting device using the ZnSe crystal substrate, in particular, the method for the heat treatment of a ZnSe crystal substrate comprising previously forming an Al film on the substrate, first subjecting the substrate to a heat treatment in a Se atmosphere and then subjecting to a heat treatment in a Zn atmosphere.
