Outline of Final Research Achievements |
In this project, we have studied an innovation of vertical-type Ge-based spin MOSFET with Schottky-tunnel contacts. We have obtained three main research results. First, using MBE technique, we have fabricated all-epitaxial ferromagnet/Ge/ferromagnet vertical stacked structures for the first time. Next, spin injection and detection through p-Ge/ferromagnet vertical structures can be demonstrated. This is the first observation of spin transport in p-Ge. Finally, using ferromagnet/Ge/ferromagnet vertical stacked structures, we have observed spin-dependent transport depending on magnetization configuration between ferromagnets. This can be observed up to room temperature. Since the spin signals at room temperature is still small, we should enhance them by making some efforts such as the suppression of spin relaxation in Ge and the use of highly spin-polarized spin injector and detector.
