Graphene-Silicon Schottky diodes for photodetection
Antonio Di Bartolomeo, Giuseppe Luongo, Laura Iemmo +1
We present the optoelectronic characterization of two graphene/silicon Schottky junctions, fabricated by transferring CVD-graphene on flat and nanotip-patterned n-Si substrates, re…
Field emission from self-catalyzed GaAs nanowires
Filippo Giubileo, Antonio Di Bartolomeo, Laura Iemmo +5
We report observation of field emission from self-catalyzed GaAs nanowires grown on Si (111). The measurements are realized inside a scanning electron microscope chamber with nano-…
Graphene enhanced field emission from InP nanocrystals
L. Iemmo, A. Di Bartolomeo, F. Giubileo +6
We report the observation of field emission from InP nanocrystals epitaxially grown on an array of p-Si nanotips. We prove that field emission can be enhanced by covering the InP n…
Hysteresis in the transfer characteristics of MoS2 transistors
Antonio Di Bartolomeo, Luca Genovese, Filippo Giubileo +4
We investigate the origin of the hysteresis observed in the transfer characteristics of back-gated field-effect transistors with an exfoliated MoS2 channel. We find that the hyster…
Transport and field emission properties of buckypapers obtained from aligned carbon nanotubes
F. Giubileo, L. Iemmo, G. Luongo +6
We produce 120 um thick buckypapers from aligned carbon nanotubes. Transport characteristics evidence ohmic behavior in a wide temperature range, non linearity appearing in the cur…
