Peculiarities of the fabrication of semiconductor materials under microgravity conditions

摘要

Possibilities of producing semi-conductive monocrystals by electron-beam crucible-free zonal melting under micro-gravitation conditions, as well as use of these conditions for study of some fundamental problems of crystallization physics are considered. Space technological installation for treatment of materials by the electron-beam heating is described. Its technical characteristics, as well as the results of investigations, carried out under the earth conditions, the structure and electrophysical properties of silicon monocrystalls, produced by this method under earth conditions, are given.
