| Outline of Final Research Achievements |
In this study, based on the results obtained in former spin-valve device (close to spin-FET)measurements (high spin injection efficiency, 11 %, and long spin diffusion length, over 5 maivcro-m), we have studied several problems toward the realization of spin-FET as well as spin-FET based Inverter devices. Most difficult problems are found in the device fabrication process such as making ferromagnetic electrode with reliable magnetic properties on the InGaAs hetero-junction surfaces and top-gates via Al2O3 insulator film. As a result, we have succeeded to make spin valve, spin-FET and prototype spin-Inverter devices.
