Highly Sensitive Mid-Infrared Photodetector Enabled by Plasmonic Hot Carriers in the First Atmospheric Window

The first atmospheric window of 3-5 μm in the mid-infrared（MIR） spectral range pertains to crucial application fields,with particular scientific and technological importance.However,conventional narrow-bandgap semiconductors operating at this band,represented by mercury cadmium telluride and indium antimonide,suffer from limited specific detectivity at room temperature and hindered optoelectronic integration.In this study,a plasmonic hot electron-empowered MIR photodetector based on Al-doped ZnO...     

无粘性土的应力矢量本构模型(Ⅱ)——应用

将史宏彦等提出的无粘性土的应力矢量本构模型应用于分析多种复杂应力路径下材料的变形问题。结果表明，此模型不仅能够很好地反映无粘性土的应力应变非线形、硬化性、剪缩剪胀性、与应力路径的相关性、主应力与主应变增量方向之间的非共轴性以及球偏应力与变形的耦合性等主要变形特性，而且也能够同时考虑主应力轴的旋转和中主应力对土的变形及强度的影响。模型预测结果与试验结果之间的良好吻合表明了该模型的广泛适用性。
