Abstract
Formation enthalpies ΔHv of single vacancies in all AIBIIIC2VI chalcopyrite structure compounds are estimated using the macroscopic cavity model. A comparison with atomic sublimation enthalpies ΔHsub of the BIII and CVI atoms derived from existing partial vapour pressure data shows that within the accuracy of this data and the theoretical calculations the relation ΔHv ⪆ ΔHsub is fulfilled as expected from general considerations.Keywords
