Abstract
This work presents a simulation analysis of nitride multi-quantum-well near-infrared light-emitting diodes (LEDs) with an emission wavelength of 1300 nm using Crosslight-APSYS software. The polarization electric field at the quantum wells was effectively tuned by adopting an Al0.02Ga0.19In0.79N quaternaries compound as the barrier for the In0.78GaN quantum wells, resulting in a near-zero polarization electric field. This approach significantly reduced band bending and increased the overlap of electron-hole wave functions within the quantum wells. Consequently, the internal quantum efficiency (IQE) in the nitride near-infrared LED improved, and the droop effect was significantly reduced. The Auger recombination mechanism that influences the droop effect was further analyzed. This provides an efficient approach for the development of high-performance InGaN-based near-infrared light-emitting diodes with high indium content.
