How are minority carriers injected without a p-n junction? Answer: Metal Semiconductor Band diagram of Schottky diode under (a)equilibrium conditions, (b)forward bias, and (c)strong forward bias Under strong forward bias, minority carrier injection occurs strong forward-bias is needed for minority carrier injection Can Schottky contacts emit light? If yes, under which circumstances? Are there other circumstances under which Schottky contacts emit light? OE F Schubert, Rensselaer Polytechnic Institute, 2003© E. F.
