Outline of Final Research Achievements

Significant milestones achieved in this research project are: (1) creation of Si spin MOS transistors, which can replace conventional Si CMOS devices, and its room temperature operations, and (2) observation of spincaloritronic effects in Si, which allows solving a tremendous waste heat issue in Si CMOS devices.
