Stacking boundaries and transport in bilayer graphene
P. San-Jose, R. V. Gorbachev, A. K. Geim +2
Pristine bilayer graphene behaves in some instances as an insulator with a transport gap of a few meV. This behaviour has been interpreted as the result of an intrinsic electronic…
Accurate determination of electron-hole asymmetry and next-nearest neighbor hopping in graphene
A. Kretinin, G. L. Yu, R. Jalil +7
The next-nearest neighbor hopping term t' determines a magnitude and, hence, importance of several phenomena in graphene, which include self-doping due to broken bonds and the Klei…
Van der Waals heterostructures
A. K. Geim, I. V. Grigorieva
Research on graphene and other two-dimensional atomic crystals is intense and likely to remain one of the hottest topics in condensed matter physics and materials science for many…
The effect of electron dielectric response on the quantum capacitance of graphene in a strong magnetic field
Brian Skinner, G. L. Yu, A. V. Kretinin +3
The quantum capacitance of graphene can be negative when the graphene is placed in a strong magnetic field, which is a clear experimental signature of positional correlations betwe…
Resonant tunnelling and negative differential conductance in graphene transistors
L. Britnell, R. V. Gorbachev, A. K. Geim +6
The chemical stability of graphene and other free-standing two-dimensional crystals means that they can be stacked in different combinations to produce a new class of functional ma…
Giant magneto-drag in graphene at charge neutrality
M. Titov, R. V. Gorbachev, B. N. Narozhny +9
We report experimental data and theoretical analysis of Coulomb drag between two closely positioned graphene monolayers in weak magnetic field. Close enough to the neutrality point…
