| Outline of Final Research Achievements |
In this study, we have tried highly efficient spin injection and low loss spin transport in diamond semiconductors. Spin injection efficiency into diamond became one order larger than that before by tuning surface-termination state of diamond and improving crystal quality of tunnel barriers in magnetic tunnel junctions on diamond. We have succeeded in fabricating epitaxial Mn2CoAl films, which are spin gapless semiconductors (SGS), at lower growth temperature and observed ambipolar characteristics, which is one of main characteristics of SGS. We have succeeded in fabricating graphene layers on diamond, that is important for efficient spin injection, and also found graphene/diamond junctions showed peculiar conductivity change by photo irradiation.
