Contact electrification is about the charge transfer between the surfaces of two materials in a contact-separation process. This effect has been widely utilized in particle separation and energy harvesting, where the charge transfer is preferred to be maximized. However, this effect is always undesirable in some areas such as electronic circuit systems due to the damage from the accumulated electrostatic charges. Herein, we introduced an approach to purposely manipulate the contact…

Electron Transfer in Nanoscale Contact Electrification: Effect of Temperature in the Metal–Dielectric Case

A thermionic-emission band-structure model is proposed to describe the electron transfer between two solids at different temperatures and suggests that CE can occur between two identical materials owing to the existence of a local temperature difference arising from the nanoscale rubbing of surfaces with different curvatures/roughness.

Effect of contact- and sliding-mode electrification on nanoscale charge transfer for energy harvesting

The process of charge transfer based on triboelectrification (TE) and contact electrification (CE) has been recently utilized as the basis for a new and promising energy harvesting technology, i.e.,

Contact-Electrification between Two Identical Materials: Curvature Effect.
