摘要
莫尔材料中存在的周期性超晶格结构是天然的人工量子系统。螺旋莫尔超晶格是一种层间转角可控的多层莫尔材料,螺位错的存在消除了层间壁垒的存在,突破了垂直堆叠体系电子跨层输运的结构局限,带来了独特的电子能带结构和新奇物性。与垂直堆叠的莫尔体系不同,螺旋莫尔材料具有更强的层间耦合,为探索强关联物理现象以及开发新型关联量子电子器件提供了新的平台。本文综述了近年来螺旋莫尔材料的相关研究进展。首先,基于螺位错驱动生长机制,系统总结了螺旋莫尔材料的主要制备方法;然后探讨了螺位错数量、位错夹角及衬底对螺旋结构的影响,归纳了螺旋莫尔材料的相关研究进展,包括力学应变、光学响应、电子运输以及催化性能。最后,对该领域的发展现状和面临的挑战进行了总结和展望。
The periodic superlattice structure present in Moirématerials is a natural artificial quantum system.Different from the conventional superlattice structure formed by vertical stacking of layers,the spiral Moirésuperlattice breaks the interlayer barriers and breaks through the structural limitations of the vertically stacked system,which brings unique electronic energy band structure and novel properties,and enables it to show great potential in the fields of condensed matter physics,optoelectronics,and materials science.Currently,the study of spiral Moirésuperlattice is developing towards richer material systems,more variable interlayer angles and wider application of properties.This opens up new paths for probing light-matter interactions and developing new semiconductor devices.In this review,we summarize the current preparation methods(e.g.,chemical vapor deposition,liquid phase method)of spiral Moirésuperlattice materials from the growth mechanism driven by spiral dislocations,discuss in detail the effects of the number of spiral dislocations,dislocation angle,and the substrate on the spiral structure,summarize a variety of novel properties found in the experiments,including the mechanical strain,optical response,electron transport,and catalytic properties.And finally,we provide a summary of the material's development,current status,and outlook the challenges.
