Abstract

In this review, we address the optical signatures of defects in two-dimensional transition metal dichalcogenides (2D TMDs), whether they occur unintentionally during growth or are deliberately introduced post-growth. We detail their primary responses as probed by photoluminescence (PL), magneto-PL, Raman, tip-enhanced PL and Raman, and nonlinear spectroscopies. Defects significantly impact the electronic, vibrational, magneto-optical, and nonlinear properties of TMDs, influencing outcomes based on application needs. This comprehensive overview highlights the distinctive optical fingerprints of various defects, providing guidance for their identification and characterization. Additionally, we discuss new optical phenomena induced by defects in TMD monolayers and future challenges in defect engineering for these materials. The insights from this review underscore the potential of TMDs for technological applications, with advancements in spectroscopy and defect engineering driving future innovations and enhancing our understanding of these materials.

原子薄过渡金属二硫族化合物缺陷的光谱学研究

在这篇综述中，我们讨论了二维过渡金属二硫族化合物（2D TMDs）中缺陷的光学特征，无论它们是在生长过程中无意发生的还是在生长后故意引入的。我们通过光致发光（PL）、磁致发光、拉曼、尖端增强的PL和拉曼以及非线性光谱来探测它们的主要响应。缺陷会显著影响tmd的电子、振动、磁光和非线性特性，从而影响基于应用需求的结果。这一全面的概述突出了各种缺陷的独特的光学指纹，为它们的识别和表征提供了指导。此外，我们还讨论了由TMD单层缺陷引起的新的光学现象以及这些材料的缺陷工程的未来挑战。这篇综述的见解强调了tmd在技术应用方面的潜力，光谱学和缺陷工程的进步推动了未来的创新，增强了我们对这些材料的理解。

期刊介绍： Applied Physics Reviews (APR) is a journal featuring articles on critical topics in experimental or theoretical research in applied physics and applications of physics to other scientific and engineering branches. The publication includes two main types of articles: Original Research: These articles report on high-quality, novel research studies that are of significant interest to the applied physics community. Reviews: Review articles in APR can either be authoritative and comprehensive assessments of established areas of applied physics or short, timely reviews of recent advances in established fields or emerging areas of applied physics.
