Charge carrier density noise in graphene: effect of localized/delocalized traps
Francesco M. D. Pellegrino, Giuseppe Falci, Elisabetta Paladino
Graphene-based devices show low-frequency noise in several electronic transport properties, such as mobility and charge carrier concentration. The recent outburst of experime…
Low-frequency critical current noise in graphene Josephson junctions in the open-circuit gate voltage limit
Francesco M. D. Pellegrino, Giuseppe Falci, Elisabetta Paladino
We investigate critical current noise in short ballistic graphene Josephson junctions in the open-circuit gate-voltage limit within the McWorther model. We find flicker noise in a…
Ultrafast optical spectroscopy of semiconducting and plasmonic nanostructures and their hybrids
Daniele Catone, Lorenzo Di Mario, Faustino Martelli +7
The knowledge of the carrier dynamics in nanostructures is of fundamental importance for the development of (opto)electronic devices. This is true for semiconducting nanostructures…
Optical properties and carrier dynamics in Co-doped ZnO nanorods
Aswathi K. Sivan, Alejandro Galan-Gonzalez, Lorenzo Di Mario +12
The controlled modification of the electronic properties of ZnO nanorods via transition metal doping is reported. A series of ZnO nanorods were synthesized by chemical bath growth…
Plasmon induced resonant effects on the optical properties of Ag-decorated ZnSe nanowires
Aswathi K Sivan, Lorenzo Di Mario, Daniele Catone +4
In this work we present how the optical properties of ZnSe nanowires are modified by the presence of Ag nanoparticles on the sidewalls of the ZnSe nanowires. In particular we show…
