摘要
在微重力条件下生长了 ZnTe:Cu 晶体对其进行了光学和能谱分析在晶锭尾部最大结晶区对其进行了组分分析.对于尾部的轴向分量在空间样品中 Cu 的成分均匀性优于地面样品并且 Te/ Zn 比的样品高于空间样品.尾部空间样品中 Cu 的径向成分均匀性优于地面样品且 Te 偏析更为严重.
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 of the tail section is better than that of the ground sample, and the Te segregation of the ground sample is more serious.
