Two-dimensional Janus-type materials and their heterostructures

二维 Janus 材料代表了二维材料中的重大创新。通过打破镜像对称性，二维材料的电子特性发生显着变化，这使得它们对于基础研究和许多应用都非常有趣。然而，迄今为止，只有极少数的 Janus 2D 材料被制造出来，因此关于其性能的实验数据也很少。该项目旨在通过扩大可用的Janus 2D材料的数量、开发高质量Janus单层异质结构的制造方法、表征和控制其物理性质以及大幅扩展此类材料的结构-功能关系的知识，为这一新领域的进展做出重大贡献。

Two-dimensional Janus materials represent a significant innovation among 2D materials. By breaking the mirror symmetry, the electronic properties of the constituent 2D materials are significantly changed, making them extremely interesting for both fundamental research and many applications. To date, however, only very few Janus 2D materials have been fabricated and experimental data on their properties is thus scarce. This project aims to contribute significantly to the progress in this novel field by expanding the number of available Janus 2D materials, developing fabrication methods for heterostructures of high-quality Janus monolayers, characterizing and controlling their physical properties, and substantially expanding the knowledge of structure-function relationships in this class of materials.
