Anisotype surface-barrier n-Cd 0.5Zn 0.5O/p-CdTe heterojunctions are fabricated by the high-frequency sputtering of a Cd 0.5Zn 0.5O alloy film onto a freshly cleaved single-crystal CdTe surface. The main electrical properties of the heterojunctions are studied and the dominant mechanisms of charge transport are established, namely, the multistage tunnel-recombination mechanism under forward bias, Frenkel-Pool emission, and tunneling under forward bias. The influence of the surface electrically active states at the heterojunction interface is analyzed and their surface concentration is evaluated: N ss ~ 10 14 cm -2.
