PbTe/PbSnTe液相外延溶液

Study on PbTe/PbSnTe LPE Solution

为了研究多元红外探测器响应波长均匀性,用PbTe/PbSnTe液相外延单相溶液进行了实验。本文论述了单相溶液的配比、结晶温度的测定、外延温度曲线、外延Pb_(1-x)Sn_xTe薄膜和溶液的分析以及用该溶液制备的PbTe/PbSnTe异质光伏16元红外探测器的性能。

This paper described the stoichiometry of the single phase solution and the calculated x value of the epi-layer, the pratical stoichiometry of the solution, the determination of the crystallization temperature and the epitaxial temperature curve. The Pb_(1-x)Sn_xTe epi-layer and the solution have been analysed in detail. Finally, the performance of 16-element PV heterojunction IR detector fabricated on the PbTe/PbSnTe thus obtained has been presented.
