'Raman spectra' refers to the characteristic patterns of light scattering that arise from interactions between a laser beam and the chemical composition of a sample. These spectra can be influenced by various factors such as excitation wavelengths and background fluorescence, and are commonly used in...
Especially, graphene and graphite have been reported with negative thermal expansion, significant phonon anharmonicity and electron–phonon coupling14,15,40. Meanwhile, the doping exhibits significant influence on Raman features and temperature-dependent Raman spectra of graphene, and graphite can be ...

demonstrated a matter-wave interferometer with laser-cooled sodium atoms using the mechanical effects of stimulated Raman transitions. SRS has even been used to observe time-resolved vibrational spectra of the primary isomerisation of retinal in the visual pigment rhodopsin [50]....
Furthermore, for a given stacking, the band structure significantly changes as a function of the number of layers, N (ref. 6). An even wider range of properties is accessible by creating MLG with stacking arrangements different from those common in natural graphite. We refer to these as ...
significantly alter the spectroscopic signature of hydrated minerals and generate electronic defects in different minerals35. These defects are responsible for a strong increase in the intensity of the continuum signal in the Raman spectra, as well as a decrease in the Raman signal-to-background ...
In summary, we have presented an overview of the Raman spectroscopy in graphene, discussing the theoretical background associated with the first-order and the double resonance Raman scattering mechanisms that gives rise to the main features in the Raman spectra of graphene, and presenting some recent...
