Conductance in multiwall carbon nanotubes and semiconductor nanowires : evidence of a universal tunneling barrier
J. -F. Dayen, X. Hoffer, T. L. Wade +2
Electronic transport in multiwall carbon nanotubes and semiconductor nanowires was compared. In both cases, the non ohmic behavior of the conductance, the so-called zero bias anoma…

First Order Transition of the Vortex Lattice in Disordered Bi-2212 Crystals
C. J. van der Beek, I. Abalosheva, M. Konczykowski +3
Using differential magneto-optical imaging, we address the question of mesoscopic inhomogeneity in underdoped Bi-2212 single crystals. Among other features, it is shown that an ano…

"Vortex-melting front" in thin superconductors with pinning
M. V. Indenbom, E. H. Brandt, C. J. van der Beek +1
Magneto-optical observations of a second flux front, which occurs at the second peak in the magnetization of Bi_2 Sr_2 CaCu_2 O_x single crystals related to the known first order `…
