Dopant-atoms have been demonstrated to work as quantum dots (QDs) in Si nano-transistors . These systems have the fundamental property of controlling single-electron tunneling (SET), promising low-power consumption for future electronics . Alternatively, they are attractive for quantum computing, which can bring a breakthrough in computation power. For such applications, room temperature (RT) operation is required and a CMOS-compatible, robust fabrication is necessary.
Here, we first study the stability of a-few-donor QD (in this case, 3 P-donors) against fluctuations of donor number and mainly atomistic position.
