WebThe effective 3D Auger coefficient is estimated in the approximation of a spherical QD, and a good agreement with the experimental data is obtained. Semiconductor laser … WebIt is discovered that the InAs/InAlAs NWs have a very low Auger rate (ten-fold smaller than planar zincblende InAs) and a high radiative rate, which results in a high estimated 77 K peak internal quantum efficiency of 22%. This suggests that InAs-based NWs show promise as high efficiency mid-infrared emitters.
