The role of water in the preparation and stabilization of high quality phosphorene flakes
Manuel Serrano-Ruiz, Maria Caporali, Andrea Ienco +3
Water is believed to be harmful for the stability of phosphorene.On the contrary, the presence of small amount of water allows the synthesis of high-quality material in liquid exfo…
Bilayer-induced asymmetric quantum Hall effect in epitaxial graphene
Andrea Iagallo, Shinichi Tanabe, Stefano Roddaro +8
The transport properties of epitaxial graphene on SiC(0001) at quantizing magnetic fields are investigated. Devices patterned perpendicularly to SiC terraces clearly exhibit bilaye…
Large thermal biasing of individual gated nanostructures
Stefano Roddaro, Daniele Ercolani, Mian Akif Safeen +5
We demonstrate a novel nanoheating scheme that yields very large and uniform temperature gradients up to about 1K every 100nm, in an architecture which is compatible with the field…
High-contrast Aharonov-Bohm oscillations in the acoustoelectric transport regime
E. Strambini, E. Ligarò, F. Beltram +4
Phase-coherent acoustoelectric transport is reported.Aharonov-Bohm oscillations in the acoustoelectric current with visibility exceeding 100% were observed in mesoscopic GaAs rings…
Lasing in planar semiconductor diodes
Giorgio De Simoni, Lukas Mahler, Vincenzo Piazza +5
We present a planar laser diode based on a simple fabrication scheme compatible with virtually any geometry accessible by standard semiconductor lithography technique. We show that…
Revealing the atomic structure of the buffer layer between SiC(0001) and epitaxial graphene
Sarah Goler, Camilla Coletti, Vincenzo Piazza +8
On the SiC(0001) surface (the silicon face of SiC), epitaxial graphene is obtained by sublimation of Si from the substrate. The graphene film is separated from the bulk by a carbon…
