摘要

我们研究了利用化学气相沉积（CVD）合成的单层 MoS2 样品的稳定性，随后在环境条件下对其进行了有机分子修饰。通过使用光致发光光谱 (PL)、拉曼光谱和原子力显微镜 (AFM) 分析样品的光学特征和表面质量，我们观察到用有机分子修饰单层 MoS2 是稳定的，并能在环境条件下长期保持其光学特征。此外，我们还展示了有机分子诱导效应的可逆性，因为加热改性样品可恢复其原始光学特征，这表明原始单层 MoS2 的光学特性得以重建。

Stability and reversibility of organic molecule modifications of CVD-synthesized monolayer MoS₂.

We investigated the stability of monolayer MoS₂samples synthesized using chemical vapor deposition (CVD) and subsequently modified with organic molecules under ambient conditions. By analyzing the optical signatures of the samples using photoluminescence spectroscopy (PL), Raman spectroscopy, and surface quality using atomic force microscopy (AFM), we observed that this modification of monolayer MoS₂with organic molecules is stable and retains its optical signature over time under ambient conditions. Furthermore, we show the reversibility of the effects induced by the organic molecules, as heating the modified samples restores their original optical signatures, indicating the re-establishment of the optical properties of the pristine monolayer MoS₂.

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
