Abstract :
A new thermogradient mechanism for creation of defects in semiconductors by separation of intrinsic defects in a temperature gradient field is proposed. Experimental results for p-InSb and p-CdTe samples using Nd:YAG laser irradiation showed the role of hot charge carriers in formation of p-n junctions and A-centres in CdTe(Cl).
