4. A Si sample is doped with 6x1015 cm-3 donors and 2x1015 cm-3 acceptors. a. Find the position of the Fermi level with respect to E; (the intrinsic Fermi level) at OK and 300K. b. Draw a picture of the energy diagram, density of states, Fermi distribution, and n and p concentrations at 300K. At 300K, what is the value and sign of the Hall coefficient? 4.
