The forward current across the depletion layer of a PN junction diode consists of electrons from Ν to Ρ and holes injected from Ρ to N. The ratio of the hole current crossing the junction to the total current is known as the injection efficiency. Determine an expression for the injection efficiency as a function of: a) Na/Nd. b) The ratio of the conductivity of Ρ to that of N. Assume τp = Ο.1τn , and μp = 2.5 μn...
