The operation of resistive switches based on phase-separated blends of organic ferroelectrics and semiconductors depends significantly on the microstructure of such systems. The blend phase separates into amorphous rir-P3HT domains embedded in a crystalline P(VDF-TrFE) matrix with an unexpectedly mono-disperse domain-size distribution for a given rir-P3HT:P(VDF-TrFE) ratio. A simple model is used to interpret the out of plane current through the film as a function of blend composition.
