Optical conductivity, Drude weight and plasmons in twisted graphene bilayers
Tobias Stauber, Pablo San-Jose, Luis Brey
We numerically calculate the optical conductivity of twisted graphene bilayers within the continuum model. To obtain the imaginary part, we employ the regularized Kramers-Kronig re…
Electronic transport of folded graphene nanoribbons
Jhon W. González, Mónica Pacheco, Pedro Orellana +2
We investigate the electronic transport properties of a folded graphene nanoribbon with monolayer nanoribbon contacts. We consider two possible foldings: either the nanoribbon can…
Dielectric screening and plasmons in AA-stacked bilayer graphene
Rafael Roldan, Luis Brey
The screening properties and collective excitations (plasmons) in AA-stacked bilayer graphene are studied within the random phase approximation (RPA). Whereas long lived plasmons i…
Electronic Properties of Twisted Trilayer Graphene
E. Suárez Morell, M. Pacheco, L. Chico +1
We study the electronic properties of a twisted trilayer graphene, where two of the layers have Bernal stacking and the third one has a relative rotation with respect to the AB-sta…
