Abstract It is shown for the first time that deuterium can diffuse into GaAs from a gaseous source. Experiments performed at 500° C show two-component diffusion profiles with diffusion coefficients in the range 10−15−4×10-1cm2s−1 depending on the conductivity type of the samples. These diffusion coefficients are considerably lower than those determined after RF plasma hydrogenation. Such a slow diffusion process is related to the reaction of molecular deuterium with the sample surface leading to the dissociation of the deuterium molecules.
