Abstract
The effect of post-hydrogenation of phosphorus and boron doped a-Si films deposited by CVD has been studied by electrical conductivity and ESR. It is found that, contrary to the phosphorus case, hydrogenation decreases the conductivity of strongly boron doped specimens and reduces the intensity of the doping induced ESR g = 2.013. The results are interpreted in terms of a reduction of the number of electrically active boron atoms.
