本文给出了由（Pb1 - xLSnxL）1 - z (Se1 - yLTeyL)z组成的熔体生长Pb1 - xsSnxsSe1 - ys - Teys晶格与PbSe相匹配的固体化合物所需的相平衡数据。在450°C和540°C之间，xL值从0%到40%和yL值从0%到40%的液相线数据也给出了。当yL小于40%时，碲对液相温度的影响可以忽略不计。对于650°C和450°C生长的层，在xL = 14%时观察到锡的液固结合线xs vs xL的交叉。碲的液固结合线数据（ys vs yL）表明，yL相对于硒的偏析系数较低，小于40%，从而解释了碲对液相温度的影响有限。xL =5%， 10%和20%的晶格匹配条件分别为yL =16.4%， 25%和33.5%。在5%锡的情况下观察到显著的晶格拉动效应，预计在10%和20%锡的情况下也是如此。这种效应，再加上相对海平面较低……
The phase equilibria data necessary for growing solid compounds of Pb1−xsSnxsSe1−ys Teys lattice matched to PbSe from melts consisting of (Pb1−xLSnxL)1−z (Se1−yLTeyL)z are presented. Liquidus data for values of xL from 0% to 40% and yL from 0% to 40% for temperatures between 450 and 540 °C are also presented. The influence of tellurium on the liquidus temperature is shown to be negligible at least for yL less than 40%. A crossover in the liquid‐solid tie lines of tin, xs vs xL, for layers grown at 650 and 450 °C is observed at xL equal to 14%. The liquid‐solid tie‐line data for tellurium, ys vs yL, show a low segregation coefficient relative to selenium for yL less than 40%, thus explaining tellurium’s limited influence on the liquidus temperature. The lattice‐matching conditions for xL =5%, 10%, and 20% are yL =16.4%, 25%, and 33.5%, respectively. A significant lattice‐pulling effect is observed for the 5% tin case and is expected for the 10% and 20% tin cases. This effect, along with the low relative se...
