단일 전자 트랜지스터 (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 쿨롱 차단 효과로 인해 극도로 높은 감도와 낮은 전력 소비가 가능해집니다.
