Journal ArticleDOI
Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: 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.
Journal ArticleDOI
Nanometric optical tweezers based on nanostructured substrates
TL;DR: In this article, the first experimental realization of three-dimensional nanometric optical tweezers that are based on nanostructured substrates was reported, which achieved nanoscale control of entities at significantly smaller laser powers and open new avenues for nanomanipulation of fragile biological objects.
Journal ArticleDOI
Nanofabricated media with negative permeability at visible frequencies
Alexander N. Grigorenko,Andre K. Geim,Helen F. Gleeson,Y. Zhang,A. A. Firsov,Igor Khrushchev,Jovana Petrović +6 more
TL;DR: 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.
Journal ArticleDOI
Antisymmetric plasmon resonance in coupled gold nanoparticles as a sensitive tool for detection of local index of refraction
Alexander N. Grigorenko,Helen F. Gleeson,Y. Zhang,Nicholas W. Roberts,A. R. Sidorov,A. A. Panteleev +5 more
TL;DR: In this article, a nanofabricated regular array of coupled gold nanopillars is employed to detect local indices of refraction of different liquids using a shift of an antisymmetric plasmon resonance peak observed in the reflection spectra.
