Abstract:The ZnTe:Cu crystals grown under microgravity and on ground are characterized by optical and energy dispersive spectrum analysis. The radial and axial spectra of the largest crystal at the end of the ingot are analyzed. For the axial component of the tail section, the compositional uniformity of Cu in the space sample is better than that of the ground sample, and the Te/Zn ratio of the ground sample is higher than that of the space sample. The radial compositional uniformity of Cu in the space sample in the tail section is better than that of the ground sample, and the Te segregation of the ground sample is more serious.
