Effect of 13C isotope doping on the optical phonon modes in graphene: Localization and Raman spectroscopy

The effect of [superscript 13]C isotope impurities on the phonon properties of graphene is discussed theoretically. We calculated the values of the phonon lifetimes due to isotope impurity scattering for all values of densities, isotopic masses, and for all wave vectors using second-order perturbati...
