Annealing of indium-implanted CdTe

Abstract
The local environment of 111In implanted in CdTe has been studied by means of the perturbed angular correlation technique as a function of annealing conditions and temperatures. It is found that the damage correlated with the implantation process anneals at 200 °C. At 250–500 °C a new defect exists which is shown to be correlated with loss of Cd and can be inhibited when the escape of Cd can be suppressed. Outdiffusion of In starts at about 500 °C, and at 650 °C almost no In remains in the sample. These results agree with, and add to, published results on the annealing of In-implanted CdTe obtained by other techniques.
