Abstract
Measurements of Faraday Rotation (FR) in amorphous As2Se3, as a function of photon energy are reported. In the bulk material the temperature dependence of the FR and the derived energy gap EFRg is investigated in the range 3-300 K. For EFRg a temperature coefficient of 2.4 x 10-4 eV/K is found. In amorphous films the FR could be measured through the energy range where the sign of the FR-angle is reversed. The photon energy corresponding to zero FR is in agreement with the gap value calculated from the measurements in bulk material, taking into account the expected differences between bulk and film.
