Abstract
We present electro-optical characterization (by deep level transient s pectroscopy, deep level optical spectroscopy and photo-induced current transient spectroscopy) on vanadium doped CdTe and CdZnTe crystals pr epared by the vertical Bridgman method for photorefractive application s. Two main electron traps at 0.95 and 0.78 eV were detected and chara cterized. These levels are strongly involved in the photorefractive ef fect of CdTe doped with V, and led to distinguish two classes of cryst als.
