## Homework Statement

Calculate Efi with respect to the center of the bandgap in silicon for t= 200, 400, 600 kelvin.

## Homework Equations

ni = Nc e^-((Ec- Ef)/(kt))

k = boltzman constant

t= temperature in kelvin

Ec = energy level of the conduction band

ef= fermi energy level

ni= carrier concentration

Nc = densitiy of states in conduction band
