Negative activation energy and dielectric signatures of excitons and excitonic Mott transitions in quantum confined laser structures
Mostly, optical spectroscopies are used to investigate the physics of excitons, whereas their electrical evidences are hardly explored. Here, we examined a forward bias activated differential capacitance response of GaInP/AlGaInP based multi-quantum well laser diodes to trace the presence of exciton...
