中文摘要	Local resistance switching in WO3 films has been studied based on the conducting atomic force microscope technique. Special attention was paid to the formation/reproducibility of local conduction regions on the metal-oxide interface for repeated setting-resetting operations and the effects of microscopic inhomogeneity. It is found that most of the conducting spots prefer to stay where they were once formed. However, only a minority of them (similar to 30%) are repeatable in resistance values for the writing-erasing cycling. According to the resistance switching behaviours, five kinds of locations can be classified in total, and they are inactive regions, weak transition regions, weak to stable transition regions, stable transition regions and irregular transition regions. A further analysis shows the preferential locations of conduction spots at protuberant grains.
