Abstract
This paper reports on the both possible applications of molybdenum oxide (MoOx) thin films in combination with hole or electron conducting CdTe. The high quality ohmic contancts and strongly rectifying photodiodes were prepared by the DC magnetron sputtering of MoOx thin films onto freshly cleaved p- and n-type CdTe single crystal substrates. The analysis of DC and AC electrical properties of the MoOx/ p-CdTe ohmic contact was carried out. The dominating current transport mechanisms through the MoOx/p-CdTe heterojunction at forward and reverse bias were determined. The unoptimized heterojunction photodiode showed promising rectifying and photoelectrical characteristics for practical application in the photoconductive mode. (© 2016 WILEY-VCH Verlag GmbH &Co.
