Raman spectroscopy as a sensitive and convenient technology, has been used for characterization of the structure and properties of graphene successfully. This review focuses on doing a simple summary in Raman spectroscopy research of graphene on two aspects of deposited on different substrates and doping. Although the G peak and 2D peak of Raman spectroscopy in different substrates has deviation in different degree, by observing Raman spectroscopy of indium tin oxide, sapphire, and glass substrate graphene, the conclusion that 2D peak can determine the layer of graphene still applied. Doping can change the charged state of graphene which makes graphene show the hole type (p) or electronic (n) doped features. The doping category of graphene is described qualitatively and quantitatively with carrier concentration of graphene by observing the change of graphene Raman spectroscopy. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
