A depth resolved investigation of hydrogen uptake in carbon based nanostructures by soft-to-hard photoemission spectroscopy
Orlando Castellano, Alice Apponi, Luca Cecchini +11
Hydrogen chemisorption on graphitic carbon modifies the carbon orbital hybridization from sp2 to sp3, altering both structural and electronic properties. Understanding not only the…
Towards Low-Energy Electron High-Resolution Spectroscopy with Transition-Edge Sensors
R. Ammendola, A. Apponi, G. Benato +62
We present a study of the energy resolution of transition-edge sensors (TESs) for the detection of electrons in the 100 eV kinetic energy range. The TES is a Ti-Au bilayer with an…
Hydrogenated carbon structures as directional sub-GeV dark matter detectors
Tomás Arias, Antonino Bellinvia, Gianluca Cavoto +5
We propose hydrogenated carbon structures as targets with a remarkable sensitivity to dark matter-nucleon interactions, in the mass range between the 1 MeV and 100 MeV. The ejectio…
Stability of Highly Hydrogenated Monolayer Graphene in Ultra-High Vacuum and in Air
Alice Apponi, Orlando Castellano, Daniele Paoloni +20
The stability of hydrogenated monolayer graphene was investigated via X-ray photoemission spectroscopy (XPS) for two different environmental conditions: ultra-high vacuum (UHV) and…
Detection of Low-Energy Electrons with Transition-Edge Sensors
Carlo Pepe, Benedetta Corcione, Francesco Pandolfi +9
We present the first detection of electrons with kinetic energy in the 100 eV range with transition-edge sensors (TESs). This has been achieved with a m T…
