Engineering Physics Annotation << Back Research of dependence of the external quantum exit of radiating diodes from current density O.I. Rabinovich, V.P. Sushkov Investigation of quantum efficiency dependence of emitting diodes (ED) (in visible region – LED, in ultraviolet – UVED) based on AlGaInN heterostructure, on current density using computer simulation was carried out. The model explaining quantum efficiency decrease with the current density rising is proposed. E-mail: rabinwork@mail.ru
