text: Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact
electrification (CE) at the nanoscale, but converting KPFM voltage maps to charge
density maps is nontrivial due to long-range forces and complex system geometry.
Here we present a strategy using finite-element method (FEM) simulations to determine
the Green's function of the KPFM probe/insulator/ground system, which allows us
to quantitatively extract surface charge. Testing our approach with synthetic
data, we find that accounting for the atomic force microscope (AFM) tip, cone,
and cantilever is necessary to recover a known input and that existing methods
lead to gross miscalculation or even the incorrect sign of the underlying charge.
Applying it to experimental data, we demonstrate its capacity to extract realistic
surface charge densities and fine details from contact-charged surfaces. Our method
gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative
charge data over a range of experimental conditions, enabling quantitative CE
at the nanoscale.

text: 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 mesoscale correlations affect not only the magnitude of charge transfer
but also the fluctuations—suppressing otherwise overwhelming charge-transfer variability
that is not observed experimentally. We furthermore propose a generic theoretical
mechanism by which the mesoscale features might emerge, which is qualitatively
consistent with other proposals in the literature.
