Abstract

The authors have carried out extensive measurements of electron triboemission from the scratching of ceramics and semiconductors that are briefly summarized in this paper. Analysis of the frequency-domain distribution of typical triboemission count-pulse outputs suggested that their occurrence is not Poisson's (e.g., it is not random). This paper presents a study on the hypothesis of deterministic-chaos origin for triboemission data. Electron triboemission outputs from the ceramics alumina, sapphire, silicon nitride and the semiconductors Si and Ge are analyzed by means of extracting deterministic-chaos metrics. The results suggest that the low-level electron-emission components may be described by multiplicative processes of random initiation, while the superimposed large burst-type components may be of deterministic origin.
