Raman Spectroscopic Studies of Graphene and Related Nanomaterials
グラフェンおよびナノ材料の顕微ラマン分光解析
Graphene, the two dimensional carbon, is one of the most actively studied nanomaterials due to its many fascinating properties and potential technological applications. Raman spectroscopy and imaging has become a simple yet powerful, non-invasive method to characterize graphene and a wide range of other nanomaterials. This paper will review examples of using Raman spectroscopy and imaging to study a broad range of structural, phononic, electronic, and thermal properties of graphene, drawing mostly from work in my laboratory on both exfoliated graphene and synthetic graphene grown by chemical vapor deposition. Combining electronic transport and gating with Raman measurements also gives a powerful technique to characterize electronphonon coupling. Similar experimental techniques can be applied to many other “beyond-graphene” 2D materials and their Van der Waals (VdW) coupled heterostructures.
