| Research Abstract |
The objective of this research is to create materials and devices with nonvolatile memory and reconfigurable functions, in particular, spin-polarized-current-controlled devices. By introducing magnetic elements and ferromagnetic materials into semiconductors and device structures, we fabricate new functional materials and devices that use spin degrees of freedom as well as charge transport of carriers, particularly spin-polarized currents. More specifically, we establish the basic material and process technologies of, 1) III-V based heterojunction-type spin transistors, 2) group-IV based MOSFET-type spin devices, and 3) single-electron spin transistors based on ferromagnetic nanoparticles/semiconductor granular materials.
