Topological electric current from time-dependent elastic deformations in graphene
Abolhassan Vaezi, Nima Abedpour, Reza Asgari +2
We show the possibility of inducing an edge charge current by applying time-dependent strain in gapped graphene samples preserving time reversal symmetry. We demonstrate that this…
Strains and pseudo-magnetic fields in circular graphene rings
Nima Abedpour, Reza Asgari, F. Guinea
We demonstrate that circular graphene ring under a shear stress displays strong pseudo-magnetic fields. We calculate the pseudo-magnetic field both from continuum elasticity theory…
Conductance of bilayer graphene in the presence of a magnetic field: Effects of disorder
H. Hatami, N. Abedpour, A. Qaiumzadeh +1
We investigate the electronic transport properties of unbiased and biased bilayer graphene nanoribbon in n-p and n-n junctions subject to a perpendicular magnetic field. Using the…
Irreversibility in response to forces acting on graphene sheets
N. Abedpour, Reza Asgari, M. R. Rahim Tabar
The amount of rippling in graphene sheets is related to the interactions with the substrate or with the suspending structure. Here, we report on an irreversibility in the response…
Conductance of disordered graphene superlattice
N. Abedpour, Ayoub Esmailpour, Reza Asgari +1
We study the conductance of disordered graphene superlattices with short-range structural correlations. The system consists of electron- and hole-doped graphenes of various thickne…
Roughness of undoped graphene and its short-range induced gauge field
N. Abedpour, M. Neek-Amal, Reza Asgari +3
We present both numerical and analytical study of graphene roughness with a crystal structure including atoms. The roughness can effectively result in a random gau…
