Multiple charge carrier species as a possible cause for triboelectric cycles
Juan Carlos Sobarzo, Scott Waitukaitis
The tendency of materials to order in triboelectric series has prompted suggestions that contact electrification might have a single, unified underlying description. However, the p…
Quantifying nanoscale charge density features of contact-charged surfaces with an FEM/KPFM-hybrid approach
Felix Pertl, Juan Carlos Sobarzo, Lubuna Shafeek +2
Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact electrification at the nanoscale, but converting KPFM voltage maps to charge density maps is non-trivia…
Quantitatively consistent, scale-spanning model for same-material tribocharging
Galien Grosjean, Sebastian Wald, Juan Carlos Sobarzo +1
By rigorously accounting for mesoscale spatial correlations in donor/acceptor surface properties, we develop a scale-spanning model for same-material tribocharging. We find that me…
