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…
The role of contact resistance in graphene field-effect devices
Filippo Giubileo, Antonio Di Bartolomeo
The extremely high carrier mobility and the unique band structure, make graphene very useful for field-effect transistor applications. According to several works, the primary limit…
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…
Hybrid Graphene/Silicon Schottky photodiode with intrinsic gating effect
Antonio Di Bartolomeo, Giuseppe Luongo, Filippo Giubileo +5
We propose a hybrid device consisting of a graphene/silicon (Gr/Si) Schottky diode in parallel with a Gr/SiO2/Si capacitor for high-performance photodetection. The device, fabricat…
