Fig. 5: The correlations between charge transfer at the liquid–solid interface and other parameters including pinning factor, work function and dielectric constant.
From: Understanding contact electrification at liquid–solid interfaces from surface electronic structure
a The linear correlation between charge transfer and dielectric function that is based on the introduction of the pinning factor. Q represents the charge transfer, ε represents the dielectric constant of the materials. P represents the pinning factor. b The correlation between work function, calculated dielectric constant, and charge transfer (Q).
