Abstract

original image

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.
