Critical currents in graphene ribbon Josephson junctions

Most of the remarkable transport properties of graphene have to do with its particular band structure at low energies: the undoped system has a finite number of Fermi points, placed at the corner of the [...]

Resistance measurements and weak localization in long SWNTs

Gabrielli P.G., Gabrielli S., Gabrielli P.G., Gabrielli S., Lisi N., ENEA, IT

In the theory of the 1-d electron systems, called Tomonaga-Luttinger-liquid (LL), the correlated electron state is characterized by a parameter g that measures the strength of the interaction between the electrons (g=1 for non-interacting electron [...]

Low-T Quantum Transport in Carbon Nanotubes: Role of Vacuum Fluctuations in Loss of Phase Coherence

Gabrielli P.G., Gabrielli S., Gabrielli P.G., Gabrielli S., ENEA, IT

Among the items in the design of new generation of electronic devices there are the measurement and understanding of the current-voltage response of an electronic circuit in which molecular systems like carbon nanotubes (CNTs) act [...]
