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

, 2018
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 ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
