Ohmic and Rectifying Contacts on High Resistivity P-Type Cadmium Telluride
Published online by Cambridge University Press: 15 February 2011
Abstract
Ohmic and rectifying contacts on high resistivity etched P-type cadmium telluride have been studied in order to produce diode structures.For this,we have first investigated the properties of gold contacts obtained by chemical reactions of CdTe dippedin gold chloride.Both electrical characterization and structure have been analyzed as a function of the experimental conditions of the contact deposition.The results can be interpreted in terms of a current flow enhanced by tunnelling through the Au-CdTe junction and related to the structure of the interface a few tens of nanometer below the gold contact. In addition,several rectifying contacts have been investigated , in order to achieve a structure having low leakage current.
