Abstract

The authors report upon highly reproducible, unipolar resistive-switching random access memory with narrow voltage distributions using Au/ZnO nanorods/Au structures. The ZnO nanorods resistive switching layer was prepared by a simple spin-coating process on a sol-gel seed layer, and from its size confinement effect, this device showed narrow set/reset voltage distributions and low voltage operations compared with Au/ZnO thin film/Au structures. With this electrical uniformity, the device exhibited good reliabilities such as long retention (> 70000 sec) and high endurance (> 5000 cycles).
