Abstract

AbstractIn order to explain the peculiar characteristics of iodidely synthesized PbTe and SnTe crystals a model for their interaction with iodine is suggested. It is based on the assumption that PbI and I, respectively SnI and I, resulting from the PbI2 (SnI2) dissociations, are incorporated independently and specifically in the crystals: in PbTe prevails the PbI‐incorporation; in SnTe — the incorporation of I + VSn. This difference is connected with the thermodynamic stability of the PbTe and SnTe crystal lattices.
