Electrostatic force microscopy and potentiometry of realistic nanostructured systems
M. Lucchesi, G. Privitera, M. Labardi +3
We investigate the dependency of electrostatic interaction forces on applied potentials in Electrostatic Force Microscopy (EFM) as well as in related local potentiometry techniques…
Demonstration of an electrostatic-shielded cantilever
P. Pingue, V. Piazza, P. Baschieri +4
The fabrication and performances of cantilevered probes with reduced parasitic capacitance starting from a commercial Si3N4 cantilever chip is presented. Nanomachining and metal de…
Colors Of Graphite On Silicon Dioxide
S. Roddaro, P. Pingue, V. Piazza +2
Monoatomic layers of graphite can be electrically contacted and used as building blocks for new promising devices. These experiment are today possible thanks to the fact that very…
Resonant Transport in Nb/GaAs/AlGaAs/GaAs Microstructures
F. Giazotto, P. Pingue, F. Beltram +4
Resonant transport in a hybrid semiconductor-superconductor microstructure grown by MBE on GaAs is presented. This structure experimentally realizes the prototype system originally…
Evidence of diffusive fractal aggregation of TiO2 nanoparticles by femtosecond laser ablation at ambient conditions
G. L. Celardo, D. Archetti, G. Ferrini +3
The specific mechanisms which leads to the formation of fractal nanostructures by pulsed laser deposition remain elusive despite intense research efforts, motivated mainly by the t…
Coulomb-Blockade directional coupler
P. Pingue, V. Piazza, F. Beltram +3
A tunable directional coupler based on Coulomb Blockade effect is presented. Two electron waveguides are coupled by a quantum dot to an injector waveguide. Electron confinement is…
Low field magnetotransport in strained Si/SiGe cavities
G. Scappucci, L. Di Gaspare, F. Evangelisti +6
Low field magnetotransport revealing signatures of ballistic transport effects in strained Si/SiGe cavities is investigated. We fabricated strained Si/SiGe cavities by confining a…
Coherent transport in Nb/delta-doped-GaAs hybrid microstructures
F. Giazotto, P. Pingue, F. Beltram
Coherent transport in Nb/GaAs superconductor-semiconductor microstructures is presented. The structures fabrication procedure is based on delta-doped layers grown by molecular-beam…
