Superionic Conductors as Fast, Repetitive Opening Switches

Abstract

The use of superionic conductors, in particular Ag13I9W2O8, as fast, repetitive, optically triggered opening switches for power conditioning applications in spacecraft has been investigated. It was found, unexpectedly, that serious shelf-life degradation in this material exists, caused by conversion of Ag(+) ions to neutral silver. This degradation can be minimized by storage at 150 C or above, but irreversible conversion from Ag13I9W2O8 to Ag4I2WO4 and Ag5IW2O8 is greatly accelerated by the presence of laser light.
