Abstract

The authors have carried out extensive characterizations of negatively-charged triboemission from scratching of ceramics and of semiconductors in high vacuum. This experimental work explores if the measured triboemission-output evolution may relate to worn surface features. Delays on the start of the triboemission outputs from an alumina-ball sliding on alumina-disk with respect to those from the diamond scratching of alumina are consistent with the observed surface modifications. Electron triboemission features are discussed, and it is concluded that new findings on the reduction of electron work function during dry sliding can help understanding electron triboemission and its origin.
