| Abstract: | Graphene's unique electronic structure gives rise to distinct plasmonic properties, making it especially significant for applications in optoelectronic devices, sensors, and as a promising candidate for THz lasers. Raman spectroscopy is a valuable tool for probing the behavior of graphene. Our primary objective in studying Raman spectroscopy in graphene is to extract information from surface plasmon waves (SPWs) that propagate along the graphene surface when exposed to a laser beam, particularly within the THz range (referred to here as THz-SPWs). This approach enables the simultaneous characterization of graphene properties. By employing a mathematical framework based on the Vlasov equation, we establish a method to correlate the Raman-scattered wave with THz-SPWs and intrinsic graphene features, allowing comprehensive investigation of key parameters such as graphene Fermi energy, THz-SPWs frequency and wavelength, Raman scattering angle, incident beam characteristics, and substrate effects.
