On chain models for contact electrification [PDF]
Journal of Physics: Condensed Matter, 2022 Abstract An exact analytical model of charge dynamics for a chain of atoms with asymmetric hopping terms is presented. Analytic and numeric results are shown to give rise to similar dynamics in both the absence and presence of electron interactions.

The Charging Events in Contact-Separation Electrification [PDF]
Scientific Reports, 2018 AbstractContact electrification (CE)—charging of surfaces that are contacted and separated, is a common phenomenon, however it is not completely understood yet. Recent studies using surface imaging techniques and chemical analysis revealed a ‘spatial’ bipolar distribution of charges at the nano dimension, which made a paradigm shift in the field ...
