Dominant Phonon Wavevectors and Strain-induced Splitting of the 2D Graphene Raman Mode

Rohit Narula, Nicola Bonini, Nicola Marzari +1

The dominant phonon wavevectors $q^{\ast }$ probed by the 2D Raman mode of graphene are highly anisotropic and rotate with the orientation of the polarizer:analyzer direction relative…
