Carrier densities

The free carrier density increases at high temperatures for which the intrinsic density approaches the net doping density and decreases at low temperatures due to incomplete ionization of the dopants The carrier density and Fermi energy are shown in Figure 2 6 9 for silicon doped with 10 16 cm-3 donors and 10 15 cm-3 acceptors
