X-ray study of the superionic phase transition in CuCrS2
- 60 Downloads
The temperature disorder of copper ions in the CuCrS2 superionic conductor was studied by X-ray analysis. It is shown that the average square deviations of atoms sharply increase and become comparable with the distance between neighbouring tetrahedral sites when CuCrS2 transforms into the superionic phase. It is also established that the direction of maximum deviation of atoms is close to the direction connecting the tetrahedral positions.
