The phenomenon of contact electrification (CE) has been known for thousands of years, but the nature of the charge carriers and their transfer mechanisms are still under debate. Here, the CE and triboelectric charging process are studied for a metal–dielectric case at different thermal conditions by using atomic force microscopy and Kelvin probe force microscopy. The charge transfer process at the nanoscale is found to follow the modified thermionic‐emission model. In particular, the focus here… 
Electron Transfer in Nanoscale Contact Electrification: Photon Excitation Effect
The results suggest that there exists a threshold photon energy for releasing the triboelectric charges from the surface, which is 4.1 eV, and a photoelectron emission model is proposed to describe light-induced charge decay on a dielectric surface.
Probing Contact‐Electrification‐Induced Electron and Ion Transfers at a Liquid–Solid Interface
It is demonstrated that electron transfer plays the dominant role during CE between liquids and solids, which directly impacts the traditional understanding of the formation of an electric double layer at a liquid-solid interface in physical chemistry.
Dielectric Manipulated Charge Dynamics in Contact Electrification
Surface charge density has been demonstrated to be significantly impacted by the dielectric properties of tribomaterials. However, the ambiguous physical mechanism of dielectric manipulated charge
Effects of Surface Functional Groups on Electron Transfer at Liquid-Solid Interfacial Contact Electrification.
The discoveries in this work support the "two-step" model about the formation of an electric double-layer (Wang model), in which the electron transfer occurs first when the liquids contact the solids for the very first time.


On the Electron‐Transfer Mechanism in the Contact‐Electrification Effect
A new method is reported to quantitatively investigate real-time charge transfer in CE via triboelectric nanogenerator as a function of temperature, which reveals that electron transfer is the dominant process for CE between two inorganic solids.
Manipulating nanoscale contact electrification by an applied electric field.
The modulation effect of the electric field on contact electrification is enhanced for a thinner dielectric layer and can potentially be utilized to enhance the output performance of energy harvesting devices or nullify contact electric charge transfer in applications where this effect is undesirable.
Tribo-electric charging of dielectric solids of identical composition
Despite its long history and importance in many areas of science and technology, there is no agreement on the mechanisms responsible for tribo-electric charging, including especially the
Electrostatic charging due to separation of ions at interfaces: contact electrification of ionic electrets.
This Review proposes--as a still-unproved hypothesis--that this ion-transfer mechanism may also explain the ubiquitous contact electrification ("static electricity") of materials, such as organic polymers, that do not explicitly have ions at their surface.
Bipolar charge transfer induced by water: experimental and first-principles studies.
It was determined through experimental and first-principles calculations that water can also reverse the polarity of transferred charges and cause a bipolar charge transfer.
Contact electrification across metal-dielectric and dielectric-dielectric interfaces
An apparatus is described by means of which a spherical dielectric surface can be compressed under various loads against either a plane metal disk or a plane dielectric disk. A transfer of electric

This report is a study of the kinetics of contact charging resulting from the rolling of millimeter-sized metallic spheres on flat surfaces of polystyrene (PS). Charging was studied (i) for different
