Starting with the isolation of a single sheet of graphene, the study of layered materials has been one of the most active areas of condensed matter physics, chemistry, and materials science. Single-layer transition-metal dichalcogenides are direct-gap semiconducting analogs of graphene that exhibit novel electronic and optical properties. These features provide exciting opportunities for the discovery of both new fundamental physical phenomena as well as innovative device platforms. Here, we review the progress associated with the creation and use of a simple microscopic framework for describing the optical and excitonic behavior of few-layer transition-metal dichalcogenides, which is based on symmetry, band structure, and the effective interactions between charge carriers in these materials. This approach provides an often quantitative account of experiments that probe the physics associated with strong electron–hole interactions in these quasi two-dimensional systems and has been successfully employed by many groups to both describe and predict emergent excitonic behavior in these layered semiconducting systems.

原子薄过渡金属双硫属元素化物的光学和激子性质

从隔离单层石墨烯开始,分层材料的研究一直是凝聚态物理,化学和材料科学领域最活跃的领域之一。单层过渡金属二卤化物是石墨烯的直接间隙半导体类似物,具有新颖的电子和光学性质。这些功能为发现新的基本物理现象以及创新的设备平台提供了令人兴奋的机会。在这里,我们回顾与建立和使用一个简单的微观框架来描述少数层过渡金属二卤化金属的光学和激子行为有关的进展,该框架基于对称性,能带结构以及电荷载流子之间的有效相互作用。这些材料。
