2μm InGaSb/AlGaAsSb 量子阱激光器理想因子的研究 = Investigation on ideality factor of 2 µm InGaSb/AlGaAsSb quantum well laser

展示了一种低阈值(~131 A/cm2)2 μm InGaSb/AlGaAsSb单量子阱(Single Quantum Well, SQW)激光器, 并对该激光器的理想因子n进行了研究。激光器的总体理想因子n由中央pn结的理想因子n和n型GaSb衬底与n型金属之间形成的整流结的理想因子n两部分组成。当温度从20 ℃升高到80 ℃时, 激光器的总体理想因子n从4.0降低至3.3。该结果与所使用的理论模型以及独立的GaSb材料整流结(pn结、GaSb/金属结等)理想因子n的数值是相吻合的。2 µm InGaSb/AlGaAsSb single quantum well(SQW) laser wit...
