In 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 PbI 2 (SnI 2 ) dissociations, are incorporated independently and specifically in the crystals: in PbTe prevails the PbI‐incorporation; in SnTe — the incorporation of I + V Sn . This difference is connected with the thermodynamic stability of the PbTe and SnTe crystal lattices.
