Abstract

The results of studies of the electrical and optical characteristics of the original and irradiated by γ-quanta 𝐶𝑜60 of high-efficiency InGaN/GaN blue light-emitting diodes with quantum wells are presented. Possible mechanisms for the appearance of singularities in current-voltage characteristics at low temperatures (T ≤ 180 °K) are discussed. It was found that the process of radiative degradation of electroluminescence is accompanied by an increase in the carrier temperature Te and an increase in the activation energy of electroluminescence.

Keywords: InGaN/GaN; Electrical and Optical Characteristics; Irradiated by γ-quanta 𝐶𝑜60
