Giant spin accumulation in silicon nonlocal spin-transport devices
A. Spiesser, H. Saito, Y. Fujita +4
Although the electrical injection, transport and detection of spins in silicon have been achieved, the induced spin accumulation was much smaller than expected and desired, limitin…
Non-linear spin transport in a rectifying ferromagnet/semiconductor Schottky contact
R. Jansen, A. Spiesser, H. Saito +1
The electrical creation and detection of spin accumulation in ferromagnet/semiconductor Schottky contacts that exhibit highly non-linear and rectifying electrical transport is eval…
Large spin accumulation voltages in epitaxial Mn5Ge3 contacts on Ge without oxide tunnel barrier
A. Spiesser, H. Saito, R. Jansen +2
Spin injection in high-quality epitaxial Mn5Ge3 Schottky contacts on n-type Ge has been investigated using a three-terminal Hanle effect measurement. Clear Hanle and inverted Hanle…
Electrical spin injection in p-type Si using Fe/MgO contacts
Aurelie Spiesser, Sandeep Sharmaa, Hidekazu Saito +3
We report the successful electrical creation of spin polarization in p-type Si at room temperature by using an epitaxial MgO(001) tunnel barrier and Fe(001) electrode. Reflection h…
Injection and detection of spin in a semiconductor by tunneling via interface states
R. Jansen, A. M. Deac, H. Saito +1
Injection and detection of spin accumulation in a semiconductor having localized states at the interface is evaluated. Spin transport from a ferromagnetic contact by sequential, tw…
Thermal spin current and magnetothermopower by Seebeck spin tunneling
R. Jansen, A. M. Deac, H. Saito +1
The recently observed Seebeck spin tunneling, the thermoelectric analog of spin-polarized tunneling, is described. The fundamental origin is the spin dependence of the Seebeck coef…
