Observation of field emission from GeSn nanoparticles epitaxially grown on silicon nanopillar arrays
Antonio Di Bartolomeo, Maurizio Passacantando, Gang Niu +4
We apply molecular beam epitaxy to grow GeSn-nanoparticles on top of Si-nanopillars patterned onto p-type Si wafers. We use X-ray photoelectron spectroscopy to confirm a metallic b…
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…
Side-gate leakage and field emission in all-graphene field effect transistors on SiO2/Si substrate
Antonio Di Bartolomeo, Filippo Giubileo, Laura Iemmo +6
We fabricate planar all-graphene field-effect transistors with self-aligned side-gates at 100 nm from the main graphene conductive channel, using a single lithographic step. We dem…
