Unformatted text preview: are equal and greater than the energy relaxation time. e) The scattering time, the momentum relaxation time, and the energy relaxation time are all equal. 5) Consider a semiconductor that is so heavily doped that degenerate carrier statistics are needed. How does the non ­degenerate expression for the screening length compare to the degenerate expression? a) The non ­degenerate expression gives a longer screening length. b) The non degenerate expression g...
