Abstract

The steady state photoconductivity σ_p of n-type, p-type and intrinsic a-Si:H has been studied up to photocarrier generation rates of G=5×10²⁷ cm^-3s^-1. In the 20ppm B₂H₆/SiH₄ p-type sample photoconduction switches from holes at low G to electrons at high G. The electron photoconduction at high G is increased by n-type and decreased by p-type doping. This is explained by the charge state of the dominant electron recombination centers. The σ_p(G) curves of doped and intrinsic a-Si:H merge at the highest G used.
