摘要

采用化学气相沉积的方法在铜催化剂上制备了不同层数的石墨烯样品及其在石墨烯平面上的相对旋转。用拉曼光谱分析了所得石墨烯结构的性质。主峰的位置和形状随层数及其旋转而变化，这表明层间相互作用的性质发生了变化。附加峰作为石墨烯层扭转角的函数进行了研究。确定所研究的扭曲结构的独特特征是优化可扩展合成和生产石墨烯基纳米电子器件的必要步骤。

Raman Spectroscopy of Multilayer Graphene Structures with Various Twist Angles Between Layers

Graphene samples with various numbers of layers and their relative rotation in the graphene plane were obtained by chemical vapor deposition on a copper catalyst. The properties of the obtained graphene structures were revealed by Raman spectroscopy. The position and shape of the main peaks changed depending on the number of layers and their rotation, which indicated a change in the nature of the interaction between the layers. Additional peaks were studied as a function of the twist angle of the graphene layers. Determining the distinctive characteristics of the studied twisted structures is a necessary step in optimizing the scalable synthesis and production of graphene-based nanoelectronic devices.
