Raman characterization of defects and dopants in graphene (2015, background): “where k is the wave vector of the electron (measured from the K or K′ point), and P is the polarization vector of the incident (scattered) field for the absorption (emission) process [63].”
Defect characterization in graphene and carbon nanotubes using Raman spectroscopy (2010, result): “However, similar results have already been shown for monolayer graphene (Casiraghi et al. 2009; Gupta et al. 2009).”
Photoluminescence intensity of single-wall carbon nanotubes (2006, background): “The calculation of the photon-absorption and emission matrix element is based on our previous paper.[10] However, we have since then added some factors to give the relative intensity per unit length of a SWNT within a relaxation time.”
Dirac electronic states in graphene systems: optical spectroscopy studies (2010, background): “When considering the linearly polarized light, the contribution of individual k-conserving transitions to the total optical conductivity depends on the angle between the given momentum k and the vector of light polarization [51], but the universal conductivity is restored after integration over all ”
