Raman imaging of doping domains in graphene on SiO2
C. Stampfer, L. Wirtz, A. Jungen +4
We present spatially resolved Raman images of the G and 2D lines of single-layer graphene flakes. The spatial fluctuations of G and 2D lines are correlated and are thus shown to be…
Tunable Coulomb blockade in nanostructured graphene
C. Stampfer, J. Guettinger, F. Molitor +3
We report on Coulomb blockade and Coulomb diamond measurements on an etched, tunable single-layer graphene quantum dot. The device consisting of a graphene island connected via two…
Diffractive paths for weak localization in quantum billiards
Iva Brezinova, Christoph Stampfer, Ludger Wirtz +2
We study the weak localization effect in quantum transport through a clean ballistic cavity with regular classical dynamics. We address the question which paths account for the sup…
