Quantitative Ultrafast Electron-Temperature Dynamics in Photo-Excited Au Nanoparticles
Maria Sygletou, Stefania Benedetti, Marzia Ferrera +11
The femtosecond evolution of the electronic temperature of laser-excited gold nanoparticles is measured, by means of ultrafast time-resolved photoemission spectroscopy induced by e…
Ripple morphology of graphitic surfaces: a comparison between few-layer graphene and HOPG
N. Haghighian, D. Convertino, V. Miseikis +5
The surface structure of Few-Layer Graphene (FLG) epitaxially grown on the C-face of SiC has been investigated by TM-AFM in ambient air and upon interaction with diluted aqueous so…
Fast detection of water nanopockets underneath wet-transferred graphene
Michele Magnozzi, Niloofar Haghighian, Vaidotas Miseikis +4
We report an investigation of the graphene/substrate interface morphology in large-area polycrystalline graphene grown by chemical-vapour deposition and wet-transferred onto Si waf…
Correlated evolution of structure and mechanical loss of a sputtered silica film
Massimo Granata, Elodie Coillet, Valérie Martinez +10
Energy dissipation in amorphous coatings severely affects high-precision optical and quantum transducers. In order to isolate the source of coating loss, we performed an extensive…
Rapid CVD growth of millimetre-sized single crystal graphene using a cold-wall reactor
Vaidotas Miseikis, Domenica Convertino, Neeraj Mishra +8
In this work we present a simple pathway to obtain large single-crystal graphene on copper (Cu) foils with high growth rates using a commercially available cold-wall chemical vapou…
Study of the isotropic contribution to the analysis of photoelectron diffraction experiments at the ALOISA beamline
F. Bruno, L. Floreano, A. Verdini +5
The angular distribution of the intensity in photoemission experiments is affected by electron diffraction patterns and by a smoothly varying ISO contribution originated by both in…
