Space charge and breakdown of poly-p-xylylene thin film

The breakdown strength of PPX (poly-p-xylylene) and space charge effects have been investigated. Temperature and thickness dependences of the breakdown strength of PPX supported avalanching as the breakdown mechanism. This is consistent with the results on high-field conduction of PPX. The prestress effect revealed a large influence of space charge on the breakdown strength of PPX, and dependence on the rest time was observed as well.<
