A semiconductor contains acceptors and the hole concentration is 1 x1016 /cm3. Assume that the density of states in the valence band, Nv, is 10¹⁹ /cm³. How far above the valence band in eV does the Fermi energy Ef lie at 300K?
Consider a semiconductor, germanium, with a bandgap Eg=0.66eV and equal density of states in the conduction band and valence bands with Nc=Nv=10¹⁹ /cm³. The temperature is 300K.
What is the value of the intrinsic carrier concentration?
If the number of electrons n is 10¹⁷ /cm³, what is the value of the hole concentration p?
