On the structure and transformation of the orange form of Sb₂S₃ layers

Abstract

X-ray diffraction study showed that the mange modification of antimony trisulphide can neither be considered as amorphous material nor does it change into the black modification upon grinding. Thin vacuum-deposited layers, prepared by conventional thermal evaporation of the bulk material in 5 × 10⁻⁶ torr on an amorphous substrate at room temperature, were crystalline. The behaviour of the electrical conductivity with temperature in the range 25 to 190° C indicated transition points at 80, 108, 135 and 175° C.
