Evidence of inter-layer interaction in magneto-luminescence spectra of electron bilayers
Ilirjan Aliaj, Vittorio Pellegrini, Andrea Gamucci +4
Magneto-luminescence studies in electron bilayers reveal the hallmarks of the even-denominator and other quantum Hall states in the intensities and energies of the inter-band optic…
Evidence for a Spin Phase Transition at ν=0 in Bilayer Graphene
Patrick Maher, Cory R. Dean, Andrea F. Young +5
The most celebrated property of the quantum spin Hall effect is the presence of spin-polarized counter-propagating edge states. This novel edge state configuration has also been pr…
Quantitative Current-Voltage Characteristics in Molecular Junctions from First Principles
Pierre Darancet, Jonathan R. Widawsky, Hyoung Joon Choi +2
Using self-energy-corrected density functional theory (DFT) and a coherent scattering-state approach, we explain current-voltage (IV) measurements of four pyridine-Au and amine-Au…
Quantum Dots at Room Temperature carved out from Few-Layer Graphene
Amelia Barreiro, Herre S. J. van der Zant, Lieven M. K. Vandersypen
We present graphene quantum dots endowed with addition energies as large as 1.6 eV, fabricated by the controlled rupture of a graphene sheet subjected to a large electron current i…
Layer breathing modes in few-layer graphene
Chun Hung Lui, Tony F. Heinz
Layer-layer coupling plays a critical role in defining the physical properties of few-layer graphene (FLG). With respect to vibrations, the interlayer coupling is predicted to crea…
Observation of out-of-plane vibrations in few-layer graphene
Chun Hung Lui, Leandro M. Malard, SukHyun Kim +4
We report the observation of layer breathing mode (LBM) vibrations in few-layer graphene (FLG) samples of thickness from 2 to 6 layers, exhibiting both Bernal (AB) and rhombohedral…
