Second harmonic generation (SHG) of two-dimensional (2D) layered materials has attracted immense research interests due to the abilities of photon generation, manipulation, transmission, detection, and imaging for the applications of modern on-chip nanophotonic devices. Some layered materials with broken inversion symmetry associated with their 2D nature enable the development of nanophotonic and nanooptoelectronic devices based on the second harmonic generation effect. Recently, many 2D materials with broken inversion symmetry have been discovered, which not only exhibit SHG quantum effects but also greatly promote the development of nanophotonics. In this review, we review the recent developments of all 2D SHG materials, including the graphene-like family, transition metal dichalcogenides, IIIA-VIA compounds and others. We focus on their fabrication, structural characteristics, and generating mechanism and basic characteristics of SHG, associated with the main strategies to tu...

二维分层材料中的二次谐波生成

二维(2D)层状材料的二次谐波产生(SHG)吸引了巨大的研究兴趣,这是由于光子的产生,操纵,传输,检测和成像的能力,适用于现代片上纳米光子器件的应用。一些具有颠倒对称性且与它们的2D性质相关联的分层材料可以基于二次谐波生成效应来开发纳米光子和纳米光电器件。近年来,发现了许多具有颠倒对称性的二维材料,它们不仅表现出SHG量子效应,而且极大地促进了纳米光子学的发展。在这篇综述中,我们回顾了所有2D SHG材料的最新发展,包括类石墨烯家族,过渡金属二卤化碳,IIIA-VIA化合物等。
