Using a redox-switchable catenane (see picture) as an approximately one-nanometer-cubic molecular switch, two-terminal molecular switch tunnel junctions (MSTJs), which incorporate a semiconducting single-walled carbon nanotube (SWNT) as the bottom electrode and a two-micrometer wide metallic top electrode, have been fabricated. Active and remnant current-voltage measurements demonstrated that these devices can be reconfigurably switched and repeatedly cycled between high and low current states under ambient conditions.
