A one-time programmable metal-molecule-metal device, with a modified Rotaxane LB film as the functional layer, is proposed for potential use in organic programmable and fault tolerant circuits like inorganic anti-fuse devices used in field programmable gate arrays. All fabrication methods involved are low temperature processes, ensuring that this device can be integrated with other organic devices. Electrical measurements show that this device has a good one-time programming capability. Its break down voltage is 2.2V, off-state resistance is, 15kΩ, and on-state resistance is 54Ω. These characteristics come from the penetration of metal atoms into molecular film under high electronic field.
