Influence of electron irradiation with E = 2 MeV on electrophysical and optical characteristics of green InGaN/GaN LEDs
We studied light-emitting diodes (LEDs) with quantum dots маde on the basis of a solid solution of In0.21Ga0.79N. Measurements of current-voltage characteristics and electroluminescence characteristics were carried out in the range of 77 ÷ 300 K. On the current-voltage characteristics in the range o...

Summary: | We studied light-emitting diodes (LEDs) with quantum dots маde on the basis of a solid solution of In0.21Ga0.79N. Measurements of current-voltage characteristics and electroluminescence characteristics were carried out in the range of 77 ÷ 300 K. On the current-voltage characteristics in the range of 77 ÷ 150 K, areas of negative differential resistance, as well as a fine structure of radiation spectra, were detected. The results of the influence of electron irradiation (Ee = 2 MeV) on electroluminescence characteristics intensity and quantum yield of the studied samples are presented; the features of the temperature dependence of the glow intensity of irradiated LEDs were revealed. |
