- Abstract
The polytypism in layered CdInGaS4 crystals grown by chemical transport reaction has been investigated by previously developed methods of oblique-texture electron diffraction and electron diffraction rotation for single crystals. It is shown that, along with the known 1T, 2H, and 3R polytypes, the 3T and 6R polytypes are identified incorrectly when using oblique-texture electron diffraction. A single-crystal rotation study revealed that the 3T polytypes are mixtures of the 1T and 3R polytypes and the 6R polytypes are mixtures of the 2H and 3R polytypes. Different polytypes alternate strictly in the direction perpendicular to the layers. The advantages of the electron diffraction rotation in comparison with other diffraction methods in phase and structural diagnostics of polytype mixtures are shown.
