1. When an intrinsic semiconductor is doped with a trivalent impurity (p-type doping), acceptor energy levels are introduced just above the valence band. The overall energy gap remains unchanged, but the effective gap for conduction decreases due to these additional energy levels. For more visit here:Read more
