Summary form only given. CdTe:Ge ensures the largest two-beam coupling gain factor among all photorefractive semiconductors with no electric field. At the same time a large scatter of data is observed even for the samples cut from the same ingot and the ultimate values of the diffraction efficiency and gain factor are still smaller than the predicted by the theory.
