Abstract :
The realization of low resistivity and stable contacts on p-type CdTe is still challenging, especially if high annealing temperatures must be avoided. In this paper, the electrical characteristics of Sb2Te3 contacts on p-type CdTe single crystals are studied. It is found that the resistivity of the contacts is low and constant with time.
