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…
Low resistive edge contacts to CVD-grown graphene using a CMOS compatible metal
Mehrdad Shaygan, Martin Otto, Abhay A. Sagade +4
The exploitation of the excellent intrinsic electronic properties of graphene for device applications is hampered by a large contact resistance between the metal and graphene. The…
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…
Numerical Simulation of Grating Couplers for Mode Multiplexed Systems
B. Wohlfeil, S. Burger, C. Stamatiadis +4
A numerical investigation of a two dimensional integrated fiber grating coupler capable of exciting several LP fiber modes in both TE and TM polarization is presented. Simulation r…
