Journal ArticleDOI
Electronic Transport Properties of Individual Chemically Reduced Graphene Oxide Sheets
Cristina Gómez-Navarro,R. Thomas Weitz,Alexander M. Bittner,Matteo Scolari,Alf Mews,Marko Burghard,Klaus Kern +6 more
TL;DR: Comparison of multilayered sheets revealed that the conductivity of the undermost layer is reduced by a factor of more than 2 as a consequence of the interaction with the Si/SiO2 substrate.
Journal ArticleDOI
Fabry-Perot Resonances in One-Dimensional Plasmonic Nanostructures
Jens Dorfmüller,Ralf Vogelgesang,R. Thomas Weitz,Carsten Rockstuhl,Christoph Etrich,Thomas Pertsch,Falk Lederer,Klaus Kern +7 more
TL;DR: From eigenmodes well beyond quadrupolar order the combined symmetry breaking effects of oblique illumination and retardation allow the excitation of dipole forbidden, even order resonances.
Journal ArticleDOI
Organic n-Channel Transistors Based on Core-Cyanated Perylene Carboxylic Diimide Derivatives
R. Thomas Weitz,Konstantin Amsharov,Ute Zschieschang,Esther Barrena Villas,Dipak K. Goswami,Marko Burghard,Helmut Dosch,Martin Jansen,Klaus Kern,Hagen Klauk +9 more
TL;DR: It is concluded that the role of the fluorine functionalization in the air-stable n-channel operation of the transistors is different than previously thought.
Journal ArticleDOI
Electronic decoupling of an epitaxial graphene monolayer by gold intercalation
Isabella Gierz,Takayuki Suzuki,R. Thomas Weitz,Dong Su Lee,Benjamin Krauss,C. Riedl,Ulrich Starke,Hartmut Höchst,Jurgen H. Smet,Christian R. Ast,Klaus Kern,Klaus Kern +11 more
TL;DR: In this paper, it is shown that it is possible to decouple the partially sp(3)-hybridized first graphitic layer formed on the Si-terminated face of silicon carbide from the substrate by gold intercalation.
Journal ArticleDOI
Plasmonic nanostructures in aperture-less scanning near-field optical microscopy (aSNOM)
Ralf Vogelgesang,Jens Dorfmüller,Ruben Esteban,R. Thomas Weitz,Alexandre Dmitriev,Klaus Kern,Klaus Kern +6 more
TL;DR: In this paper, the use of orthogonal polarizations in excitation and detection affords us with an elegant method to map near fields of plasmonic eignenmodes and other optical phenomenta.
