Interaction of A2VB3VI semiconductor compounds with metals

It is shown that as well as in the cases of II – VI, III – VI, IV – VI and I – VI group
semiconductors the comparison of experimental results about phase relations of AV
2BVI
3
semiconductor compounds with metals and given thermodynamic calculations testifies that the
calculations of thermodynamic Gibbs potential changes in the systems AV
2BVI
3 – Me allow to
determine the presence or absence of exchange interaction in each particular system with
sufficient reliability. Such estimation becomes more reliable at the simultaneous examination of
the phase diagrams of binary systems limiting each particular ternary system and taking into
account the stability of all existing binary and ternary phases. The reasons of discrepancies
between experimental data and thermodynamic calculations are discussed.
