Resistive Switching: Resistive Switching of Individual, Chemically Synthesized TiO₂Nanoparticles (Small 48/2015)

Resistive switching of individual, spherical TiO2 nanoparticles is studied by U. Simon and co-workers. Bottom-up synthesized TiO2 particles are immobilized on a conducting substrate and individually electrically addressed by an electrode tip in an in-situ scanning electron microscope, as shown in this image by T. Pössinger. On page 6444, two switching behaviors are described, bipolar and complementary, which are associated with the inner structure of the individual particles. This opens up new opportunities for materials design.
