Transport measurements of large monocrystals of Cl-doped Cd0.8Zn0.2Te indicated that Cl donors formed DX centers in this material. Persistent photoconductivity with an annealing temperature of 130K was observed. Hall-effect experiments indicated that the persistent photoconductivity arose from a persistent increase in the density of charge carriers. The saturation density was 6 x 1016/cm3. The deep binding energy of the DX center was 0.22eV.
