Abstract
Amorphous silicon films have been prepared by ultra-clean evaporation and sputter technique enclosing different amounts of hydrogen into the films. The dark conductivity of both types of films can be reduced from 10-2 (Ωcm)-1 as deposited to values smaller than 4.10-11 (Ωcm)-1 if the films contain enough hydrogen and are annealed to about 600 K. Close to the annealing minimum of the dark conductivity a maximum of photoconductivity is observed.
