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…
Electrical transport and persistent photoconductivity in monolayer MoS2 phototransistors
Antonio Di Bartolomeo, Luca Genovese, Tobias Foller +6
We study electrical transport properties in exfoliated molybdenum disulfide (MoS2) back-gated field effect transistors at low drain bias and under different illumination intensitie…
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…
