Effect of charge memory in organic composites

详细

The effect of charge memory in composites based on polymer molecules has been investigated. Resistive switchings in sandwich samples prepared by lamination from commercially available polymers (polystyrene and poly(2,3-dihydrothieno-1,4-dioxine)-poly(styrene sulphonate) are analyzed. It is shown that the characteristic switching times in the composite samples reach several nanoseconds and the number of switchings exceeds 10⁶. Switchings are observed in electric fields much below the breakdown threshold, which indicates the absence of destructive processes in the polymer.
