Graphene, the one monolayer thick flat graphite, has been attracting much interest since it was firstly reported in 2004. Graphene has many unique properties which make it an attractive material for fundamental study as well as for potential applications. Raman spectroscopy has been extensively used to study graphene, i.e. identify graphene layer numbers; probe electronic band structure; measure the concentration of electron and hole dopants; et al. Here, we will present our results on Raman spectroscopic studies of graphene, to investigate the effect of strain, defects, doping, edge structures, stacking geometry on the properties of graphene. Our results would contribute to the better understanding of the physical and electronic properties of graphene and help the future application of graphene in micro/nano electronic devices.
