abstract:
- lang: eng
text: Models for same-material contact electrification in granular media often rely
on a local charge-driving parameter whose spatial variations lead to a stochastic
origin for charge exchange. Measuring the charge transfer from individual granular
spheres after contacts with substrates of the same material, we find instead a
“global” charging behavior, coherent over the sample’s whole surface. Cleaning
and baking samples fully resets charging magnitude and direction, which indicates
the underlying global parameter is not intrinsic to the material, but acquired
from its history. Charging behavior is randomly and irreversibly affected by changes
in relative humidity, hinting at a mechanism where adsorbates, in particular,
water, are fundamental to the charge-transfer process.
