Inas auger coefficient
WebThe zero-threshold Auger recombination channel in QDs is shown to dominate at low (below 200 K) temperature, whereas at higher temperatures the quasithreshold channel becomes dominant. The effective 3D Auger coefficient is estimated in the approximation of a spherical QD, and a good agreement with the experimental data is obtained. WebJun 4, 1998 · The Auger rate at 77 K correlates with the proximity to resonance between the energy gap and the split‐off gap. Thus the Auger coefficient in the alloy decreases with …
