Methods to suppress polarization in chlorine compensated cadmium telluride detectors

Abstract

In a first part of this paper, the different models of polarization developped in the literature are critically analyzed. Then, the origin of the responsible center, its location within the bandgap and its concentration is investigated and discussed. Finally, three methods to suppress this effect are presented, mainly surface oxidation in perhydrol of the etched sample prior to the metal deposition, evaporation of a thin SiOx layer or ion implantation.
