Outline of Final Research Achievements |
The purpose of this research was to develop silicon quantum dots of new structure, to elucidate the physics of spin-based quantum computation and to realize basic technologies for hardware. In the future we aimed to fuse existing silicon technology and quantum computer. In physics, spin relaxation mechanism peculiar to silicon quantum dot structure, electron transport characteristics involving valleys and spins were clarified. As a technique, unique quantum dot structure using Si substrate or Si / SiGe hetero substrate was fabricated. We also developed a spin manipulation technique and detection method suitable for new structures of silicon quantum dots using Si MOS type quantum dots or SiGe hetero substrates type quantum dots.
