 Since the DDCC has the capability of solving the Poisson, drift-diffusion, and thermal solver self-consistently. It will need to consider the possibility of bandgap narrowing with temperature. Therefore, we can apply the temperature dependent coefficients for the material's bandgap. Usually the temperature dependent bandgap can be expressed as 
 $Eg(T) = Eg(0) - \frac{\gamma T^{2} }{ T + \beta}$
