Abstract Scope A detailed analysis of the major existing energy gap-temperature models in semiconductors, in the literature, is presented. The evolution of such models is discussed. The physical implications of a model, its type (broadly: empirical, semi-empirical, and theoretical), its comparison with experimental values, and its accuracy across various temperature ranges and material groups are considered. Specifically, most conventional semiconductors along with several ternary, organic perovskite, chalcogenide, and a few miscellaneous semiconductors are included. The aforementioned parameters are used to determine the most effective and global model at the present time. Potential extensions of this model and avenues for future research are also discussed. The influence of scaling from 3-D to 2-D on the temperature dependence of the bandgap in semiconductors is discussed.
