Why a magnetized quantum wire can act as an active laser medium
Manvir S Kushwaha
The fundamental issues associated with the magnetoplasmon excitations are investigated in a quantum wire characterized by a confining harmonic potential and subjected to a perpendi…
Spring-block approach for nanobristle patterns
Ferenc Járai-Szabó, Emőke-Ágnes Horvát, Robert Vajtai +1
A two dimensional spring-block type model is used to model capillarity driven self-organization of nanobristles. The model reveals the role of capillarity and van der Waals forces…
Observation of a cyclotron harmonic spike in microwave-induced resistances in ultraclean GaAs/AlGaAs quantum wells
Yanhua Dai, R. R. Du, L. N. Pfeiffer +1
We report the observation of a colossal, narrow resistance peak that arises in ultraclean (mobility 3X10^7cm^2/Vs) GaAs/AlGaAs quantum wells (QWs) under millimeterwave irradiation…
Relativistic Drude Response of Photoexcited Dirac Quasiparticles in Graphene
K. M. Dani, J. Lee, R. Sharma +7
Graphene, a monolayer of carbon atoms arranged in a hexagonal pattern, provides a unique two-dimensional (2D) system exhibiting exotic phenomena such as quantum Hall effects, massl…
Graphene edge from A to Z - and the origins of nanotube chirality
Yuanyue Liu, Alex Dobrinsky, Boris I. Yakobson
The energy of arbitrary graphene edge is derived in analytical form. It contains a "chemical phase shift", determined by the chemical conditions at the edge. Direct atomistic compu…
Renormalized Energies of Superfluorescent Bursts from an Electron-Hole Magneto-plasma with High Gain in InGaAs Quantum Wells
J. -H. Kim, J. Lee, G. T. Noe +6
We study light emission properties of a population-inverted 2D electron-hole plasma in a quantizing magnetic field. We observe a series of superfluorescent bursts, discrete both in…
Polarization dependence of coherent phonon generation and detection in highly-aligned single-walled carbon nanotubes
L. G. Booshehri, C. L. Pint, G. D. Sanders +9
We have investigated the polarization dependence of the generation and detection of radial breathing mode (RBM) coherent phonons (CP) in highly-aligned single-walled carbon nanotub…
Paramagnetic centers in graphene nanoribbons prepared from longitudinal unzipping of carbon nanotubes
S. S. Rao, A. Stesmans, D. V. Kosynkin +2
Electron spin resonance (ESR) investigation of graphene nanoribbons (GNRs) prepared through longitudinal unzipping of multiwalled carbon nanotubes (MWCNTs) indicates the presence o…
Anomalous Transport and Possible Phase Transition in Palladium Nanojunctions
Gavin D. Scott, Juan J. Palacios, Douglas Natelson
Many phenomena in condensed matter are thought to result from competition between different ordered phases. Palladium is a paramagnetic metal close to both ferromagnetism and super…
Direct Measurement of Cyclotron Coherence Times of High-Mobility Two-Dimensional Electron Gases
X. Wang, D. J. Hilton, J. L. Reno +2
We have observed long-lived (~30 ps) coherent oscillations of charge carriers due to cyclotron resonance (CR) in high-mobility two-dimensional electrons in GaAs in perpendicular ma…
Shot noise suppression at room temperature in atomic-scale Au junctions
P. J. Wheeler, J. N. Russom, K. Evans +2
Shot noise encodes additional information not directly inferable from simple electronic transport measurements. Previous measurements in atomic-scale metal junctions at cryogenic t…
Finite Conductivity in Mesoscopic Hall Bars of Inverted InAs/GaSb Quantum Wells
Ivan Knez, R. R. Du, Gerard Sullivan
We have studied experimentally the low temperature conductivity of mesoscopic size InAs/GaSb quantum well Hall bar devices in the inverted regime. Using a pair of electrostatic gat…
Large Magnetic Susceptibility Anisotropy of Metallic Carbon Nanotubes
T. A. Searles, Y. Imanaka, T. Takamasu +4
Through magnetic linear dichroism spectroscopy, the magnetic susceptibility anisotropy of metallic single-walled carbon nanotubes has been extracted and found to be 2-4 times great…
