Single Molecules Can Work as Reproducible Transistors--at Room Temperature

Columbia researchers published a study today in Nature Nanotechnology that is the first to reproducibly demonstrate current blockade--the ability to switch a device from the insulating to the conducting state where charge is added and removed one electron at a time--using atomically precise molecular clusters at room temperature. The study shows that single molecules can function as reproducible circuit elements such as transistors or diodes that can easily operate at room temperature.
