Impurity induced broadening of Drude peak in strained graphene
The recent experimental study of the far-infrared transmission spectroscopy of monolayer graphene has shown that the Drude peak width increases by more than 10% per 1% of applied mechanical strain, while the Drude weight remains unchanged. We study the influence of the strain on the resonant impur...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The recent experimental study of the far-infrared transmission spectroscopy of monolayer graphene has shown
that the Drude peak width increases by more than 10% per 1% of applied mechanical strain, while the Drude
weight remains unchanged. We study the influence of the strain on the resonant impurity scattering. We propose a mechanism of augmentation of the scattering rate due to the shift in the position of resonance. Using
the Lifshitz model of substitutional impurities, we investigate changes in the Drude peak weight and width as
functions of the Fermi energy, impurity concentration and magnitude of the impurity potential. |
