Phase equilibria and liquid‐phase‐epitaxy growth of PbSnSeTe lattice‐matched to PbSe

摘要: The phase equilibria data necessary for growing solid compounds of Pb1−xsSnxsSe1−ys Teys lattice matched to PbSe from melts consisting (Pb1−xLSnxL)1−z (Se1−yLTeyL)z are presented. Liquidus values xL 0% 40% and yL temperatures between 450 540 °C also influence tellurium on the liquidus temperature is shown be negligible at least less than 40%. A crossover in liquid‐solid tie lines tin, xs vs xL, layers grown 650 450 °C observed equal 14%. tie‐line tellurium, ys yL, show a low segregation coefficient relative selenium 40%, thus explaining tellurium’s limited temperature. lattice‐matching conditions =5%, 10%, 20% =16.4%, 25%, 33.5%, respectively. significant lattice‐pulling effect 5% tin case expected 10% cases. This effect, along with se...
