X-Ray diffraction studies of Cd0.9ZN0.1Te at room temperature

Abstract

X-ray diffraction studies of Cd0.9Zn0.1Te have been made from the diffraction patterns recorded at room tempera-ture. A distinct splitting of some of the lines in Cd0.9Zn0.1Te have been found while no splitting was found in the lines for CdTe, giving evidence that the structure of Cd0.9Zn0.1Te is distorted from the zinc blende structure. Correcting for thermal vibrations, it is observed that the intensities of the diffraction lines of Cd0.9Zn0.1Te at ro-om temperature were lower than those of the lines of CdTe. This gives further evidence of the distortion in the structure of Cd0.9Zn0.1Te. The results of the X-ray diffraction studies indicate that the structure of Cd0.9Zn0.1Te at room temperature is zinc blende with a rhombohedral distortion. A model in which the Te ion is shifted from its original position is consistent with the results.
