Molecular-based electronically switchable tunnel junction devices

Solid-state molecular tunnel junction switching devices were fabricated by sandwiching LB monolayers of a bistable [2] catenane, a bistable [2] pseudorotaxane and a single station rotaxane between an n-type polysilicon bottom electrode and a titanium aluminum top electrode. All the devices showed a hysteretic current-voltage response that switched the device between high and low conductivity states although control devices exhibited no response. d
