| Research Abstract |
We have fabricated silicon-based quantum dot devices by the combination of bottom-up and top-down technologies and studied for the application of quantum information devices. It has been clarified that a piezo-valve, raicalnitridation, and dip-coating methods are effective for controlling the size, the surface oxide layer, and integration of silicon nanocrystals, respectively. We have also fabricated a nanoscale devices integrated by coupled-quantum-dots and a charge sensor single-electron-transistor, and successfully controlled the number of a few electrons in the quantum dots.
