単一電子 トランジスタ (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 クーロン 遮断効果により、極めて高い感度と低消費電力を実現します。
