We investigated the temperature dependence of the frequency of G peak in the Raman spectra of on Si/substrates. The micro-Raman spectroscopy was carried out under the 488 nm laser excitation over the temperature range from -190 to +100 degrees C. The extracted value of the temperature coefficie...
Graphene-enhanced Raman scattering (GERS) on isotopically labelled bilayer and a single layer of pristine and partially hydrogenated graphene has been studied. The hydrogenated graphene sample showed a change in relative intensities of Raman bands of Rhodamine 6 G (R6G) with different vibrational en...
The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the electron bands via a double resonant Raman process. The G peak slightly down-shifts. This allows unambiguous, high-throughput, nondestructive identification of graphene ...
In particular, this chapter will discuss Raman characterization of graphene with artificial disorder generated by irradiations such as electron-beam exposure and oxygen plasma, focusing on the defect-activated Raman D peak. 展开 被引量: 83

Both changes in the G-band can be used to determine layer thickness, however the peak position is also sensitive to strain, temperature and doping so care needs to be taken when using this band for layer evaluation. Figure 3: Raman spectra from the G-band of monolayer, bilayer, and ...
