Theory of resonant multiphonon Raman scattering in graphene We present a detailed calculation of intesities of two-phonon and four-phonon Raman peaks in graphene. Writing the low-energy Hamiltonian of the interactio... DM Basko - 《Physical Review B》 被引量: 0发表: 2008年 Erratum: Theory ...
Raman spectroscopy plays a key role in studies of graphene and related carbon systems. Graphene is perhaps the most promising material of recent times for many novel applications, including electronics. In this paper, the traditional and well established Kramers-Heisenberg-Dirac (KHD) Raman scattering...

Tip-enhanced Raman scattering (TERS) microscopy enables high-resolution optical visualization and analysis of materials at the nanoscale. Although TERS shares similarities with surface-enhanced Raman scattering (SERS), it offers unique advantages, particularly through the utilization of plasmonic TERS tips....
It is important to emphasize that ACD (different from real CD) is not the result of a single chiroptical event at the microscopic level. Rather, it is a double-scattering event consisting of subsequent birefringent and dichroic interactions. Instead, the Hamiltonian given by Eq. (2) implicitly...

Experimental and theoretical studies of the vibrational modes of carbon nanotubes are reviewed. The closing of a 2D graphene sheet into a tubule is found to lead to several new infrared (IR)- and Ramanactive modes. The number of these modes is found to depend on the tubule symmetry and not...
