Energy Gap of Intrinsic Semiconductors: Temperature Dependence

[Elliptic]

Energy gap dependence on temperature for intristic semiconductors (Si,Ge)

I need help on this topic, where to find text about this, and models that describe it (Varshni's model, linear model,...)

Here's a Google Scholar search on the subject.
