WebbThe effect of pressure (P) on the G-mode frequency (ω) of unsupported VGNs is investigated by in situ Raman spectroscopic studies up to 40 GPa using a diamond anvil cell. Above 16 GPa, discontinuity in the ω versus P curve suggests a disruption of long-range order in the graphene layers resulting in a deviation from two-dimensional layer …
WebbTwo laser lines of 514 and 633 nm with a power of 0.5 mW on the sample were employed to excite the Raman spectra. Comparing the sample spectra to that of bulk alpha-Fe2O3, the sample Raman peaks were assigned. And it was found for the top-layer that the Raman frequencies were down shifted and the peak widths broadened.

WebbRaman spectroscopy ( / ˈrɑːmən /) (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. [1] Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint … WebbThe Raman spectrum of graphene can be used to determine the number of carbon layers, the quality of the material, and the concentration of charge carriers in graphene.
