Room-temperature detection of spin accumulation in silicon across Schottky tunnel barriers using a MOSFET structure
K. Hamaya, Y. Ando, K. Masaki +5
Using a metal-oxide-semiconductor field effect transistor (MOSFET) structure with a high-quality CoFe/n^+Si contact, we systematically study spin injection and spin accumulation in…
Atomically Controlled Epitaxial Growth of Single-Crystalline Germanium Films on a Metallic Silicide
S. Yamada, K. Tanikawa, M. Miyao +1
We demonstrate high-quality epitaxial germanium (Ge) films on a metallic silicide, Fe3Si, grown directly on a Ge(111) substrate. Using molecular beam epitaxy techniques, we can obt…
Effect of the magnetic domain structure in the ferromagnetic contact on spin accumulation in silicon
Y. Ando, S. Yamada, K. Kasahara +3
We show a marked effect of the magnetic domain structure in an epitaxial CoFe contact on the spin accumulation signals in Si detected by three-terminal Hanle-effect measurements. C…
Evidence for the Presence of Spin Accumulation in Localized States at Ferromagnet-Silicon Interfaces
Y. Ando, S. Yamada, K. Kasahara +4
We experimentally show evidence for the presence of spin accumulation in localized states at ferromagnet-silicon interfaces, detected by electrical Hanle effect measurements in CoF…
