摘要

采用非平衡格林函数方法在微观水平上分析了中红外量子级联激光器中的电子输运。基于计算数据与实验数据的良好一致性，得出了下亚带载流子分布是非热态的结论，并且在冷态和热态下载流子都是从有源区提取的。估计的寿命上限为0.52 ps，这与从外形因素评估的值有很大差异。

Analysis of electronic transport in a single-phonon resonance mid-IR quantum cascade laser

Non-equilibrium Green's function method is used to analyze electronic transport in a mid-infrared quantum cascade laser on microscopic level. Basing on the excellent agreement found between calculated and experimental data, the conclusions are derived that the carrier distribution in the lower laser subband is non-thermal, and the carriers are extracted from active region both in cold and hot state. An estimate 0.52 ps of upper lifetime was found which considerably differs from the value evaluated from the form factors.
