Tunnel injection into the confined-particle states of an In1−xGaxP1−zAsz well in InP

Abstract
Tunnel injection is demonstrated into the confined‐particle states of an In1−xGaxP1−zAsz potential well, located on the p‐type side of an InP pn junction, leading to structure in the IV, dI/dV, and d2I/dV2 characteristics and to step increases in the intensity of the recombination radiation at bias voltages V corresponding to the states of the well [eVEg(InGaPAs) ∼hν<Eg(InP)].
