A study of deep centers in microplasma channels in GaP light-emitting diodes with green-emission spectrum

Аннотация

The statistical delay of microplasma breakdown in GaP light-emitting diodes with the green-emission spectrum is studied. The unusual profound effect of deep centers on the statistical delay of avalanche breakdown is observed in the temperature range of 300–380 K; this effect is caused by a variation in the charge state of these centers due to a reduction in the reverse bias applied to the p–n junction. Four deep levels are revealed and their parameters are determined.
