Electrically Tunable Band Gap in Silicene
N. D. Drummond, V. Zolyomi, V. I. Fal'ko
We report calculations of the electronic structure of silicene and the stability of its weakly buckled honeycomb lattice in an external electric field oriented perpendicular to the…
z/-z Symmetry of spin-orbit coupling and weak localization in graphene
Edward McCann, Vladimir I. Fal'ko
We show that the influence of spin-orbit (SO) coupling on the weak localization effect for electrons in graphene depends on the lack or presence of z/-z symmetry in the system. Whi…
Room temperature ballistic transport in InSb quantum well nanodevices

We report the room temperature observation of significant ballistic electron transport in shallow etched four-terminal mesoscopic devices fabricated on an InSb/AlInSb quantum well…
Selection rules for Raman-active electronic excitations in carbon nanotubes
Oleksiy Kashuba, Vladimir I. Fal'ko
Raman measurements in carbon allotropes are generally associated with the exploration of the vibrational modes. Here, we present a theory of the non-resonant inelastic light scatte…
Nanoscale spatial resolution probes for Scanning Thermal Microscopy of solid state materials
P. Tovee, M. Pumarol, D. Zeze +2
Scanning Thermal Microscopy (SThM) uses micromachined thermal sensors integrated in a force sensing cantilever with a nanoscale tip can be highly useful for exploration of thermal…

We review the effect of uniaxial strain on the low-energy electronic dispersion and Landau level structure of bilayer graphene. Based on the tight-binding approach, we derive a str…
Evidence for spin memory in the electron phase coherence in graphene
A. A. Kozikov, D. W. Horsell, E. McCann +1
We measure the dependence of the conductivity of graphene as a function of magnetic field, temperature and carrier density and discover a saturation of the dephasing length at low…
Interaction-Driven Spectrum Reconstruction in Bilayer Graphene
A. S. Mayorov, D. C. Elias, M. Mucha-Kruczynski +8
The nematic phase transition in electronic liquids, driven by Coulomb interactions, represents a new class of strongly correlated electronic ground states. We studied suspended sam…
Skipping and snake orbits of electrons: singularities and catastrophes
Nathan Davies, Aavishkar A. Patel, Alberto Cortijo +3
Near the sample edge, or a sharp magnetic field step the drift of two-dimensional electrons in a magnetic field has the form of skipping/snake orbits. We show that families of skip…
Tunable metal-insulator transition in double-layer graphene heterostructures
L. A. Ponomarenko, A. K. Geim, A. A. Zhukov +8
We report a double-layer electronic system made of two closely-spaced but electrically isolated graphene monolayers sandwiched in boron nitride. For large carrier densities in one…
