Electronic conductance of twisted bilayer nanoribbon flakes
M. Pelc, E. Suárez Morell, L. Brey +1
We study the transport properties of a twisted bilayer graphene flake contacted by two monolayer nanoribbons which act as leads. We analyze the conductance in terms of the spectra…
Electronic States of Wires and Slabs of Topological Insulators: Quantum Hall Effects and Edge Transport
L. Brey, H. A. Fertig
We develop a simple model of surface states for topological insulators, developing matching relations for states on surfaces of different orientations. The model allows one to writ…
Charge redistribution and interlayer coupling in twisted bilayer graphene under electric fields
E. Suárez Morell, P. Vargas, L. Chico +1
We investigate the electronic density redistribution of rotated bilayer graphene under a perpendicular electric field, showing that the layers are actually coupled even for large a…
Gate-controlled conductance through bilayer graphene ribbons
J. W. González, H. Santos, E. Prada +2
We study the conductance of a biased bilayer graphene flake with monolayer nanoribbon contacts. We find that the transmission through the bilayer ribbon strongly depends on the app…
Effective Time Reversal Symmetry Breaking and Energy Spectra of Graphene Armchair Rings
Tianhuan Luo, A. P. Iyengar, H. A. Fertig +1
We study the energy spectra and wavefunctions of graphene rings formed from metallic armchair ribbons, near zero energy, to search for properties which may be identified with "effe…
Conductance Through Graphene Bends and Polygons
A. Iyengar, T. Luo, H. A. Fertig +1
We investigate the transmission of electrons between conducting nanoribbon leads oriented at multiples of 60 degrees with respect to one another, connected either directly or throu…
