Hofstadter's butterfly in moire superlattices: A fractal quantum Hall effect
C. R. Dean, L. Wang, P. Maher +12
Electrons moving through a spatially periodic lattice potential develop a quantized energy spectrum consisting of discrete Bloch bands. In two dimensions, electrons moving through…
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…
Entropy density and entropy flux in near-field thermal radiation
Arvind Narayanaswamy, Yi Zheng
We propose a method to evaluate the entropy density and entropy flux in a vacuum gap between two half-spaces that takes into account influence of near-field effects, i.e., interfer…
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…
Effects of the interfacial polarization on tunneling in surface coupled quantum dots
Kuljit S. Virk, David R. Reichman, Mark S. Hybertsen
Polarization effects are included exactly in a model for a quantum dot in close proximity to a planar interface. Efficient incorporation of this potential into the Schrödinger equa…
Transport properties of individual C60-molecules
G. Géranton, C. Seiler, A. Bagrets +2
Electrical and thermal transport properties of C60 molecules are investigated with density-functional-theory based calculations. These calculations suggest that the optimum contact…
Control of valley polarization in monolayer MoS2 by optical helicity
Kin Fai Mak, Keliang He, Jie Shan +1
Electronic and spintronic devices rely on the fact that free charge carriers in solids carry electric charge and spin, respectively. There are, however, other properties of charge…
Spin-polarized electric currents in diluted magnetic semiconductor heterostructures induced by terahertz and microwave radiation
P. Olbrich, C. Zoth, P. Lutz +11
We report on the study of spin-polarized electric currents in diluted magnetic semiconductor (DMS) quantum wells subjected to an in-plane external magnetic field and illuminated by…
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…
Terahertz detection mechanism and contact capacitance of individual metallic single-walled carbon nanotubes
Joel D. Chudow, Daniel F. Santavicca, Chris B. McKitterick +2
We characterize the terahertz detection mechanism in antenna-coupled metallic single-walled carbon nanotubes. At low temperature, 4.2 K, a peak in the low-frequency differential re…
Radiative coupling and weak lasing of exciton-polariton condensates
I. L. Aleiner, B. L. Altshuler, Y. G. Rubo
In spite of having finite life-time exciton-polaritons in microcavities are known to condense at strong enough pumping of the reservoir. We present an analytical theory of such Bos…
Magnetoresistance measurements of Graphene at the Charge Neutrality Point
Yue Zhao, Paul Cadden-Zimansky, Fereshte Ghahari +1
We report on transport measurements of the insulating state that forms at the charge neutrality point of graphene in a magnetic field. Using both conventional two-terminal measurem…
Spin and valley quantum Hall ferromagnetism in graphene
Andrea F. Young, Cory R. Dean, Lei Wang +7
In a graphene Landau level (LL), strong Coulomb interactions and the fourfold spin/valley degeneracy lead to an approximate SU(4) isospin symmetry. At partial filling, exchange int…
Simultaneous Determination of Conductance and Thermopower of Single Molecule Junctions
J. R. Widawsky, P. Darancet, J. B. Neaton +1
We report the first concurrent determination of conductance (G) and thermopower (S) of single-molecule junctions via direct measurement of electrical and thermoelectric currents us…
