Experimenteller Nachweis der Temperaturfelder beim Schaltvorgang in Cu₂O und Zeitlupenstudie des thermischen Durchschlages

Abstract

The temperatures before and during the breakdown (switching) in planar Ag-Cu,O-Ag structures were determined experimentally. They were measured by means of liquid crystals and thermo-chromatic cryons as temperature indicators as wcll as measuring the intensity distribution of the emitted IR radiation. Structural changes during electrical switching were observed using a slow-motion camera. The formation of the switching channel and the movement of the liquid phase in i t were observcd. The results show that the elect.rica1 switching is due to a thermal mechanism.
