Thin films of composition AsSeΧ where 0.8 ≤ Χ ≤ 1.0 obtained by the evaporation of both crystalline and glassy As2Se3 have been examined for their high-field behaviour. The films exhibit two essentially linear I-V regions with a smooth nonlinear change over. While the initial linear region may perhaps correspond to a Poole-Frenkel emission, the very high-field linear region is likely to arise from a distortion of the band shapes and lowering of the mobility gap.
