Pb1 - yInyTe films doped during growth are produced by a modified hot-wall method. According to x-ray diffraction and electron microscopy data, the films withytot < 0.012 are single-phase. The films with ytot > 0.014 consist of two (PbTe + InTe) or three (PbTe + InTe + In2Te3) phases. The 583-K indium solubility in PbTe is determined in the ternary system Pb-In-Te. The results indicate that two pseudobinary joins, PbTe-InTe and PbTe-In2Te3 , must be examined in assessing the In solubility in PbTe.
