Abstract

The invention relates to the field of planar technology for obtaining semiconductor layers of the type A4B6, particularly to a process for obtaining the substrate of BaF2 with perfect surface.The process includes spalling and cutting of the initial substrate along the chosen crystallographic directions, mechanochemical polishing of the surface, vacuum annealing of substrate at the temperature of 973°K, during 30 min, then deposition of an additional layer of BaF2 in superhigh vacuum at the substrate temperature of 1023°K, during 3...5 min, with continuous control of the surface quality by the fast electron diffraction method.
