Abstract : In this project, the double acceptor center in neutron irradiated CdTe was studied. The variation of resistivity as a function of time was measured. The analysis of our experimental results suggests that (a) the double acceptor center includes Te-vacancy, (b) the height of the barrier is about 0.25 eV, (c) the effective range of the potential barrier is about 200A, and (d) the activation energy of motion of interstitial cadmium is estimated to be 0.74 eV. It is known that CdTe is an important compound semiconductor for solid state devices, and the authors' interests stem from the fact that it shows promise as a material for the detection of nuclear radiation.
