Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors

Advanced Science, EarlyView.
The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...
