论文摘要
二维材料为较小，更高效的设备提供了前进的路径。他们的光学和电子特性让位于摩尔定律设定的限制。等离子体是电子的集体振荡，可以将光限制在比其波长小得多的尺寸上。在这项工作中，我们探讨了MOS2的等离子特性，MOS2是来自2D材料家族的代表性候选者，称为过渡金属二核苷。高分辨率电子显微镜和光谱学提供了MOS2的等离子特性至原子量表的见解。实验结果表明，电子能量损耗谱中等离子体与带间跃迁之间的关系。密度功能理论为实验发现提供了理论支持，并就基本基础物理学提供了评论。
Two dimensional materials offer a path forward for smaller and more efficient devices. Their optical and electronic properties give way to beat the limits set in place by Moore's Law. Plasmon are the collective oscillations of electrons and can confine light to dimensions much smaller than its wavelength. In this work we explore the plasmonic properties of MoS2, a representational candidate from a family of 2D materials known as transition metal dichalcogenides. High resolution electron microscopy and spectroscopy provide insights in the plasmonic properties of MoS2 down to an atomic scale. Experimental results show the relationship between plasmons and interband transitions in the electron energy loss spectrum. Density functional theory provides a theoretical support for the experimental findings and provides commentary on the fundamental underlying physics.
