Abstract

It was found that the structure of Ga_0.5In_1.5S₃ crystals, characterized by TOTE and TOTTOOE structural types, with the replacement of 1/3 of the gallium atoms by copper atoms, the Gu_0.5Ga_0.33In_1.5S₃ structure becomes the TOTTE type (a = 3:861Ȧ , c = 30:915 Ȧ, sp. gr. P6₃mc), and with the subsequent replacement of 1/6 of the sulfur atoms by selenium, the Gu_0.5Ga_0.33In_1.5S_2.5Se_0.5 structure becomes the TOTTE type (polytype 1T: a = 3:866Ȧ, c = 18:695Ȧ, sp. gr. P3m1 and polytype 3R: a = 3:866 Ȧ, c = 56:085 Ȧ, sp. gr. R3m). The advantage of a new continuous electron diffraction rotation method for studying samples consisting of mixtures of polytypes with large weight differences is presented.
