对碲镉汞液相外延(Liquid phase epitaxy, LPE)石墨舟进行了数值模拟，计算了石墨舟温度场分布。通过在母液周围加入石英框，分析其对温度场的影响，得到了石英框壁厚与温度分布的关系。模拟发现，在母液周围加入石英框结构，可以提高外延生长界面温度场均匀性。最后，将分析结果与实验相结合，进行实验验证，成功降低了边界效应对碲镉汞薄膜的影响，外延生长出厚度极差 ..为1.4 .m、组分极差 .x不超过 0.002的长波碲镉汞薄膜。

A graphite slider boat for LPE(Liquid phase epitaxy) growth of HgCdTe films was simulated numerically in this study. The temperature distributions of the growth interface were calculated, and their features were discussed. By varying the size of the quartz capsule, the effects of a heat field were investigated. The results show that in order to obtain high uniformity of the HgCdTe films, the quartz capsule is placed in the graphite slider boat and used to increase temperature uniformity of the growth interface. Combining the simulation and experimental results, the boundary effect of the LPE was reduced. The LWIR film made of HgCdTe, whose thickness .δ is approximately 1.4 .m and composition range .x is less than 0.002, is successfully obtained.
