论文摘要
即使单个二维材料拥有各种有趣和意外的特性,此类层的堆叠也会导致范德华固体,从而将两个维度的特征与源自层间相互作用的新型特征结合在一起。在这篇局部综述中,我们涵盖了范德华异质膜的制造和表征,重点是由半导体过渡金属二核苷的单层制成的杂波。引入了研究那些异叶剂的实验和理论技术。提出了针对不同过渡金属二分法的异源结构的最新发现,并讨论了不同山谷之间可能的光学转变,Moire模式的外观和Moire Excitons的特征。对Van der Waals异质双层的引人入胜且快速发展的研究提供了将其作为新兴量子纳米材料应用所需的有希望的见解。
Even if individual two-dimensional materials own various interesting and unexpected properties, the stacking of such layers leads to van der Waals solids which unite the characteristics of two dimensions with novel features originating from the interlayer interactions. In this topical review, we cover fabrication and characterization of van der Waals heterosructures with a focus on heterobilayers made of monolayers of semiconducting transition metal dichalcogenides. Experimental and theoretical techniques to investigate those heterobilayers are introduced. Most recent findings focusing on different transition metal dichalcogenides heterostructures are presented and possible optical transitions between different valleys, appearance of moire patterns and signatures of moire excitons are discussed. The fascinating and fast growing research on van der Waals hetero-bilayers provide promising insights required for their application as emerging quantum-nano materials.
