Resumen

Two previous models used with success in Cu-III-VI2 semiconductors have been employed to study the temperature dependence of the Urbach energy in ordered compounds Cu-III3-VI5 and Cu-III5-VI8. The model which contains two variable parameters seems to explain better the data over the whole temperature range studied. However, the ordered vacancy or the donor acceptor defect pair in the cation sublattice provides new features in these compounds that need further study.
