Abstract
The generation of triboelectric current during friction of diamond probes on the surface of p-Si substrates with a native oxide layer was studied. The choice of probes with different doping, as well as substrates with different surface orientations, made it possible to establish the determining influence of the probe-surface work functions difference on the direction and value of the triboelectric current. The generation of triboelectric current occurs due to the tunneling of non-equilibrium charge carriers resulting from the chemical bonds breaking during friction. Under illumination conditions, an increase in the triboelectric current was observed, as well as the photocurrent appearance due to the charge carriers separation in the space charge region.
