X-ray powder diffraction study of defect-tetrahedral structure quaternary compound CuZnGa_3Te_6

摘要

Quaternary compound CuZnGa_3Te_6 was synthesized by the melt and anneal technique. The defect-tetrahedral structure compound crystallized in the tetragonal unit cell with possible space group I4 and Z = 4/3. Complete powder diffraction data were obtained and unit cell parameters a and c, and X-ray density were calculated. These were a = 0.5946(2) nm, c = 1.1891(5) nm, and D_x = 5.81 X 10~3 kg/m~3.
