Ein einzelnes Elektron Transistor (SET) is a switching device that uses controlled electron tunneling to manipulate the flow of single electrons. It consists of a quantum dot (the ‘island’) coupled to source and drain leads via tunnel junctions, and capacitively coupled to a gate electrode. Its operation relies on the Coulomb Blockade-Effekt, der eine hohe Empfindlichkeit und einen geringen Stromverbrauch ermöglicht.
