摘要：

Transport measurements on large single crystals of Cd0.8Zn0.2Te:Cl indicate that Cl donors form DX centers in CdZnTe. We have observed persistent photoconductivity (PPC) with;an annealing temperature T(alpha)approximate to 130 K. Hall-effect experiments indicate that the PPC arises from a persistent increase in the density of charge carriers; the saturation density is N-sat=6x10(16) cm(-3). The deep binding energy of the DX center is E(d)=0.22 eV. (C) 1995 American Institute of Physics.
