Heterostructures in an a-Si:H/InSe system were grown by the deposition of a
-Si:H films onto the surface (001) of InSe single-crystal wafers and also b
y deposition of pure indium films with their subsequent selenization, in wh
ich case InSe films were synthesized at the a-Si:H surface. The photovoltai
c effect was observed and studied for both types of heterostructures. It wa
s concluded that the heterostructures obtained may be used as wide-band pho
toconverters of radiation. (C) 2000 MAIK "Nauka/ Interperiodica".
