Effect of a Single Localized Impurity on the Local Density of States in Monolayer and Bilayer Graphene
Effect of a Single Localized Impurity on the Local Density of States in Monolayer and Bilayer Graphene
We use the T-matrix approximation to analyze the effect of a localized impurity on the local density of states in monolayer and bilayer graphene. For monolayer graphene the Friedel oscillations generated by intranodal scattering obey an inverse-square law, while the internodal ones obey an inverse law. In the Fourier transform …
