Electric Field Effect in Atomically Thin Carbon Films
Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect. Expand
Two-dimensional gas of massless Dirac fermions in graphene
This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.

Nanofabricated media with negative permeability at visible frequencies
A nanofabricated medium consisting of electromagnetically coupled pairs of gold dots with geometry carefully designed at a 10-nm level exhibits a strong magnetic response at visible-light frequencies, including a band with negative µ. Expand
Two-dimensional electron and hole gases at the surface of graphite
We report two-dimensional (2D) electron and hole gases induced at the surface of graphite by the electric field effect. The 2D gases reside within a few near-surface atomic layers and exhibitExpand
Elemental vapor-phase synthesis of nanostructured zinc oxide
We systematize experimental data on the elemental vapor-phase synthesis of zinc oxide nanocrystal arrays on substrates. This process may yield nanostructures differing in shape and dimensions, inExpand
Observation of the external-ac-current-induced dc voltage proportional to the steady current in superconducting loops
A dc voltage induced by an external ac current was observed in a system of asymmetric aluminum loops at temperatures corresponding to 0.95–0.98 of the superconducting transition temperature. TheExpand
Unusual quantum magnetic-resistive oscillations in a superconducting structure of two circular asymmetric loops in series
Abstract We measured both quantum oscillations of a rectified time-averaged direct voltage Vrec(B) and a dc voltage Vdc(B) as a function of normal magnetic field B, in a thin-film aluminum structureExpand
Rectified dc voltage versus magnetic field in a superconducting asymmetric figure-of-eight-shaped microstructure
We have measured periodic oscillations of rectified dc voltage versus magnetic field V_{dc}(B) in a superconducting aluminum thin-film circular-asymmetric figure-of-eight microstructure threaded by aExpand
Voltage plateaus on V(I) curves of long quasi-one-dimensional superconducting wires (without microwave irradiation)
Segments of an almost constant voltage (plateaus) on the V(I) curves of long quasi-one-dimensional superconducting aluminum wires placed in a magnetic field are found slightly below Tc, which areExpand
Electric-pulse-induced local conducting area and joule heating effect in VO2/Al2O3 films
Abstract We investigated the effect of an electric-pulse on the insulator–metal phase transition of VO 2 /Al 2 O 3 films using synchrotron-based infrared microspectroscopy. By monitoring theExpand
