Triboelectric charge transfer theory driven by thermoelectric effect

Physical Review Research
Despite extensive study and the practical significance of friction-driven static electricity, a quantitative triboelectric charge transfer theory has yet to be established. Here, we elucidate the detailed dynamics of triboelectric charge transfer driven by interfacial thermoelectric bias, maintaining a steady state at the interface. We demonstrate that
