Abstract

Photoconductivity response spectra of polycrystalline Ag0.5InSe2 thin films are reported. The peak and shoulders observed in the photoconductivity spectra are attributed to transitions from valence sub-bands to the conduction band. From the room-temperature spectra, the band-gap energies, spin-orbit and crystal-field parameters are determined. The temperature coefficient of the photoconductivity peak energy is 1.25 × 10-4eVK-1 in the temperature range 60–100 K. The sign of the temperature coefficient reverses around 100 K and the value is -1.23 × 10-4eVK-1 in the temperature range 100–303 K. The variations of photocurrent with applied bias voltage, illumination intensity and temperature are also studied. © 2001 Kluwer Academic Publishers
