Monte Carlo simulation of hot electron transport in III-N LEDs
We study electron dynamics in a multi-quantum well (MQW) light-emitting diode (LED) using Monte Carlo simulation and show that at strong injection, Auger recombination in the quantum wells creates a hot electron population which is still visible at the p-contact 250 nm away from the MQW. The Auger-excited electrons also generate a leakage current that is notably larger than leakage predicted by drift-diffusion, indicating that electron leakage in III-N LEDs at strong injection is predominantly caused by Auger-excited hot electrons.
