Vacuum gauge from ultrathin MoS2 transistor
A. Di Bartolomeo, A. Pelella, A. Grillo +5
We fabricate monolayer MoS2 field effect transistors and study their electric characteristics from 10^-6 Torr to atmospheric air pressure. We show that the threshold voltage of the…
Temperature and gate effects on contact resistance and mobility in graphene transistors by TLM and Y-function methods
Francesca Urban, Grzegorz Lupina, Alessandro Grillo +2
The metal-graphene contact resistance is one of the major limiting factors toward the technological exploitation of graphene in electronic devices and sensors. A high contact resis…
Environmental effects on the electrical characteristics of back-gated WSe2 field effect transistors
Francesca Urban, Lisanne Peters, Nadia Martucciello +2
We study the effect of polymer coating, pressure and temperature on the electrical characteristics of monolayer WSe2 back-gated transistors with quasi-ohmic Ni/Au contacts. We find…
Geometry Effects on Switching Currents in Superconducting Ultra Thin Films
A. Leo, N. Martucciello, A. Guarino +6
Vortex dynamics is strongly connected with the mechanisms responsible for the photon detection of superconducting devices. Indeed, the local suppression of superconductivity by pho…
Low-energy electron-irradiation effect on transport properties of graphene field effect transistor
F. Giubileo, A. Di Bartolomeo, N. Martucciello +4
We study the effects of low-energy electron beam irradiation up to 10 keV on graphene based field effect transistors. We fabricate metallic bilayer electrodes to contact mono- and…
Tunable Schottky barrier and high responsivity in graphene/Si-nanotip optoelectronic device
Antonio Di Bartolomeo, Filippo Giubileo, Giuseppe Luongo +7
We demonstrate tunable Schottky barrier height and record photo-responsivity in a new-concept device made of a single-layer CVD graphene transferred onto a matrix of nanotips patte…
