Nonlinear Electrical Spin Conversion in a Biased Ferromagnetic Tunnel Contact
R. Jansen, A. Spiesser, H. Saito +4
The conversion of spin information into electrical signals is indispensable for spintronic technologies. Spin-to-charge conversion in ferromagnetic tunnel contacts is well-describe…
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…
Anomalous scaling of spin accumulation in ferromagnetic tunnel devices with silicon and germanium
S. Sharma, A. Spiesser, S. P. Dash +6
The magnitude of spin accumulation created in semiconductors by electrical injection of spin-polarized electrons from a ferromagnetic tunnel contact is investigated, focusing on ho…
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…
Spin Accumulation in Nondegenerate and Heavily Doped p-Type Germanium
S. Iba, H. Saito, A. Spiesser +4
Spin accumulation induced in p-type germanium from Fe/MgO tunnel contacts is studied as a function of hole concentration p (10^16 - 10^19 cm-3). For all p, the contacts are free of…
