Abstract
We have proposed a semi‐empirical expression for the alloy composition and temperature dependence of the fundamental energy gap in the CuGaxIn1−xSe2 alloy system. A good agreement between theoretical predictions and available experimental data is found. It seems that such semi‐empirical expressions are of considerable importance for the analysis of results on new ternary and quaternary compounds and its alloys for which detailed studies based on a more fundamental analysis are not available.Keywords
