Observation of Single Electron Transport via Multiple Quantum States of a Silicon Quantum Dot at Room Temperature

초록

Single electron transport through multiple quantum levels is realized in a Si quantum-dot device at room-temperature conditions. The energy spacing of more than triple the omnipresent thermal energy is obtained from an extremely small ellipsoidal Si quantum dot, and high charge stability is attained through a construction of the gate-all-around structure. These properties may move us a step closer to practical. applications of quantum devices at elevated temperatures. An in-depth analysis on the transport behavior and quantum structure is presented.
