摘要

最近,基于扭曲过渡金属二卤化物(TMD)异质结构的莫伊里超晶格成为探究二维(2D)材料中新颖独特的电子现象的一个前景广阔的平台。通过堆叠具有较小扭曲角的 TMD 单层,这些超晶格会产生周期性的电子态密度调制,从而形成迷你带。这些迷你带可表现出引人入胜的特性,如平坦带、相关电子行为和非常规超导性。本综述全面概述了由扭曲 TMD 异质结构形成的莫伊里超晶格的最新进展。它涵盖了创建和研究这些超晶格的理论原理和实验技术,并探讨了它们在光电子学、量子计算和能量收集方面的潜在应用。该综述还讨论了一些关键挑战,如提高制造工艺的可扩展性和可重复性,强调了这一快速发展领域中令人兴奋的机遇和持续存在的障碍。

Progress and prospects of Moiré superlattices in twisted TMD heterostructures

Progress and prospects of Moiré superlattices in twisted TMD heterostructures

Moiré superlattices based on twisted transition metal dichalcogenide (TMD) heterostructures have recently emerged as a promising platform for probing novel and distinctive electronic phenomena in two-dimensional (2D) materials. By stacking TMD monolayers with a small twist angle, these superlattices create a periodic modulation of the electronic density of states, leading to the formation of mini bands. These mini bands can exhibit intriguing properties such as flat bands, correlated electron behavior, and unconventional superconductivity. This review provides a comprehensive overview of recent progress in Moiré superlattices formed from twisted TMD heterostructures. It covers the theoretical principles and experimental techniques for creating and studying these superlattices, and explores their potential applications in optoelectronics, quantum computing, and energy harvesting. The review also addresses key challenges, such as improving the scalability and reproducibility of the fabrication process, emphasizing the exciting opportunities and ongoing hurdles in this rapidly evolving field.
