Abstract
We have developed a simple empirical way for future device design to obtain the energy band diagram of the resonant tunneling light‐emitting diode based on our self‐consistent numerical Hartree–Fock calculations. From analysis of the light emission it is found that the transverse component (perpendicular to the sample growth direction) of the photon vector potential is very small due to translational symmetry. The optical transition between electron and hole states involves both the transitions between the conduction and valence bands and between electron and hole subbands in the quantum well. For high optical transitions, a large electric field inside the quantum well is preferred.This publication has 8 references indexed in Scilit:
