Characterization of Sb2Te3 ohmic contacts on p-type CdTe single crystals

The realization of low resistivity and stable contacts on p-type CdTe is still challenging, especially if high annealing tem- peratures must be avoided. In this paper, the electrical characteris- tics of Sb?Te? contacts on p-type CdTe single crystals are studied. It is found that the resistivity of the contacts is low and constant with time.
