Dominating electron-electron scattering enables viscous electron flow exhibiting hydrodynamic current density patterns such as Poiseuille profiles or vortices. The viscous regime has recently been observed in graphene by non-local transport experimen

International audience; If surface effects are neglected, any change of the Fermi level in a semiconductor is expected to result in an equal and opposite change of the work function. This is however not observed in general in three-dimensional semico

International audience; The charge carrier density in graphene on a dielectric substrate such as SiO2 displays inho-mogeneities, the so-called charge puddles. Because of the linear dispersion relation in monolayer graphene, the puddles are predicted

International audience; We report the coexistence of charge puddles and topographic ripples in graphene decoupled from the Ir(111) substrate it was grown on. We show the topographic and the charge disorder to be locally correlated as a result of the

We report the wet chemical deposition of single crystalline epitaxial thin films of the colossal magneto-resistive manganite La0.67Sr0.33MnO3 on the lattice-matched (001)-face of a La0.3Sr0.7Al0.65Ta0.35O3 substrate. Topographic images of these films

The intercalation of an oxide barrier between graphene and its metallic substrate for chem- ical vapor deposition is a contamination-free alternative to the transfer of graphene to dielectric supports, usually needed for the realization of electronic

We report a novel method for the fabrication of superconducting nano-devices based on niobium. The well-known difficulties of lithographic patterning of high-quality niobium are overcome by replacing the usual organic resist mask by a metallic one. T

Graphene presents a two-dimensional system whose charge carriers are subjected to a disordered potential created by random charge impurities trapped in the substrate. This impurity potential induces an inhomogeneous carrier concentration. On the othe
