Quantum theory of triboelectricityRobert AlickiAlejandro JenkinsAmerican Physical Society
We assume the refractive index of the medium is 1 (vacuum) since the wavefunctions overlap in vacuum. Conclusions A first quantum-mechanical theory for contact electrification and light emission between dielectric solids was described. The spontaneous emission rate, which is exactly equal to the ...
The key quantity in this theory is the disorder averaged "triangle function", a product of three Greens functions of electrons that represents the dc current response of electrons in one layer to charge fluctuations in a remote current-carrying layer. We find that the disorder averaged triangle ...
