二维螺旋莫尔材料研究进展
Research Progress of Two-dimensional Spiral Moiré Materials
摘要
Abstract
The periodic superlattice structure present in Moiré materials is a natural artificial quantum system.Dif-ferent from the conventional superlattice structure formed by vertical stacking of layers,the spiral Moiré superlattice 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 Moiré su-perlattice 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 meth-od)of spiral Moiré superlattice 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,summa-rize a variety of novel properties found in the experiments,including the mechanical strain,optical response,elec-tron transport,and catalytic properties.And finally,we provide a summary of the material's development,current status,and outlook the challenges.关键词
