Abstract ： Photoconductivity decay (PCD) in semiconductors is investigated by a pulsed laser with an unfocused or a focused beam. The rigorous solutions of PCD under illumination with two different types of laser beams, unfocused and focused, are derived separately. The experimental results of PCD are compared with the theory using Ge-based GaN under illumination of a pulsed Nd:YAG laser at 355nm. The experimental and numerical results are in good agreement.
