For vitreous antimony trisulfide films (thickness 6.4 to 16.1 μm) the steady‐state current‐voltage characteristics were measured. The current proportional to U 2 d −3 are interpreted in terms of space‐charge‐limited currents (SCLC) with a single trap level. It is proved that a steep current increase at the end of the square‐law region is caused by trap filling. The values of the parameters of this trapping level calculated using two independent methods – from the temperature dependence of the reduction factor θ and from the trap‐filled limit (TFL) voltage – are in close agreement. The polarization the conduction mechanism of vitreous Sb 2 S 3 films at lower temperatures are discussed.
