Abstract
Raman imaging is a powerful technique that can provide the spatial distribution of the properties of the micro-/nano- material. Different parameters of the Raman peaks, e.g. height/area, position, full width at half maximum (FWHM), and also ratios/differences between peaks, can be used to construct the Raman imaging and provide valuable information for the study of 2D materials and heterostructure. In this chapter, we will introduce the basic principle of Raman imaging, and also its application in the study of 2D materials, including the effects of thickness and stacking configurations, heterostructure and interlayer coupling, defects, strain. We will also show that Raman imaging is an ideal tool to study the growth mechanism of CVD graphene.
