Effect of back-gate on contact resistance and on channel conductance in graphene-based field-effect transistors
A. Di Bartolomeo, S. Santandrea, F. Giubileo +7
We study the contact resistance and the transfer characteristics of back-gated field effect transistors of mono- and bi-layer graphene. We measure specific contact resistivity of ~…
Field emission from single and few-layer graphene flakes
S. Santandrea, F. Giubileo, V. Grossi +5
We report the observation and characterization of field emission current from individual single- and few-layer graphene flakes laid on a flat SiO2/Si substrate. Measurements were p…
Field emission properties of as-grown multiwalled carbon nanotube films
F. Giubileo, A. Di Bartolomeo, M. Sarno +4
Multiwalled carbon nanotubes have been produced by ethylene catalytic chemical vapor deposition and used to fabricate thick and dense freestanding films ("buckypapers") by membrane…
Field emission from single multi-wall carbon nanotubes
M. Passacantando, F. Bussolotti, S. Santucci +4
Electron field emission characteristics of individual multiwalled carbon nanotubes have been investigated by a piezoelectric nanomanipulation system operating inside a scanning ele…
Local probing of the field emission stability of vertically aligned multiwalled carbon nanotubes
F. Giubileo, A. Di Bartolomeo, A. Scarfato +5
Metallic cantilever in high vacuum atomic force microscope has been used as anode for field emission experiments from densely packed vertically aligned multi-walled carbon nanotube…
Strong Coupling and Double Gap Density of States in Superconducting MgB2
F. Giubileo, D. Roditchev, W. Sacks +2
Using scanning tunneling spectroscopy at T = 4.2 K, we perform simultaneously the topographic imaging and the quasiparticle density of states (DOS) mapping in granular MgB2. We obs…
