Thin films from the (As2S3)(1-x) (AgI)(x) system have been prepared by vacuum thermal evaporation from the corresponding bulk glasses Films with less than 25 mol % of AgI are amorphous, as shown by XRD investigations The thin film morphology and surface have been investigated with SEM and AFM Sandwich systems consisting of a deposited bottom electrode, a chalcogenide film and an upper electrode have been utilized for electrical studies. The DC conductivity has been measured in a linearly increasing electrical field up to 10(8) Vm(-1), at ambient temperature. The obtained results have been interpreted with a view of Christov's theory for injected electron currents
