N-CONDUCTIVITY SILICON MONO-CRYSTALS PRODUCED BY NEUTRON IRRADIATION

摘要

A method for producing homogeneously doped silicon monocrystals, with n-conductivity, by neutron irradiation, wherein, after zone-melting in a vacuum and conversion of the polycrystalline rod into the monocrystalline form, the remaining conductivity of the rod is determined , the said rod being then exposed to controlled irradiation with thermal neutrons, based on the conductivity measurement carried out, for the purpose of obtaining the desired n-conductivity.
