Influence of the ferroelectric polarization on the electronic structure of BaTiO3 thin films
N. Barrett, J. Rault, I. Krug +5
Micrometric domains of precise ferroelectric polarization have been written into a 20 nm thick epitaxial thin film of BaTiO3(001) (BTO) on a Nb doped SrTiO3 (STO) substrate using P…
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…
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…
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…
Interface Electronic Structure in a Metal/Ferroelectric Heterostructure under Applied Bias
J. E. Rault, G. Agnus, T. Maroutian +8
The effective barrier height between an electrode and a ferroelectric (FE) depends on both macroscopic electrical properties and microscopic chemical and electronic structure. The…
