ABSTRACT
It was established that the laws of atomic hydrogen penetration from an arc reflection discharge gap with a hollow cathode and self-heating element into GaAs samples coated with a thin SiO[sub 2] film differ significantly from the laws observed for the hydrogenation of thin vanadium films. The amount of hydrogen penetrating into the SiO[sub 2]/GaAs system decreases with increasing atomic hydrogen concentration in the gas phase. This is apparently related to a decrease in the probability of hydrogen atoms penetrating into the substrate, which is suggested to drop significantly with decreasing atomic energy and/or increasing hydrogen content in a thin subsurface layer.
