Abstract
We realized lithographically-defined electrically-tunable silicon quantum dots (Si QDs) without unintentional localized potentials by improving device structures and fabrication techniques. Carrier density was tuned with a top gate and QD-potentials were controlled with the side gates. We succeeded in observing spin-related tunneling phenomena using the double QD device.
