The operation of resistive switches based on phase‐separated blends of organic ferroelectrics and semiconductors depends significantly on the microstructure of such systems. On page 1887 , Kamal Asadi and co‐workers show that the preferred bicontinuouse microstructure is formed by spinodal‐decomposition phase separation of the blend. The cover image shows the corresponding microstructure probed by atomic force microscopy: the smooth valley is the featureless amorphous semiconductor phase surrounded by a crystalline ferroelectric matrix.
