Abstract:
Photoassisted atomic switches (PASs) are those produced using photoconductive organic materials. However, the use of solid photoconductive materials and the formation of a large Ag conductive bridge lead to the formation of large voids during the shrinking of Ag conductive bridges; this may degrade the performance of PASs. A low-melting-point organic semiconductor is used as a molten photoconductive material, and self-assembled ITO nanowires are used as transparent electrodes. Stable atomic switching is observed only under light irradiation.
