Abstract
The effect of samarium doping on the local structure and morphological features of the surface of a Se95Te5 chalcogenide glassy semiconductor film is investigated by X-ray diffraction analysis and atomic force microscopy, and the effect of doping on the current flow through Al–Se95Te5〈Sm〉–Te structures is examined by measuring the I–V characteristics in the steady-state mode. The results obtained are interpreted using Lampert’s theory of injection currents, the Elliott void-cluster model, and the Mott and Street charged defects model proposed for chalcogenide glasses.
