Abstract

The current-voltage characteristics of nickel-Se1−xTex-organic semiconductorgold (aluminum) heterostructures and the dependence of these characteristics on the temperature and illumination have been investigated. The Se1−xTex layer is a a variband structure with a band-gap gradient of up to 4.l04 eV/cm. A photoelectromotive force (photo-emf) and a thermoelectromotive force have been found to exist in the heterostructures studied. The mechanism of charge transfer is discussed.
