Well-width dependence of valley splitting in Si/SiGe quantum wells
Kohei Sasaki, Ryuichi Masutomi, Kiyohiko Toyama +3
The valley splitting in Si two-dimensional electron systems is studied using Si/SiGe single quantum wells (QWs) with different well widths. The energy gaps for 4 and 5.3 nm QWs, ob…
Electrical Detection and Magnetic-Field Control of Spin States in Phosphorus-Doped Silicon
H. Morishita, L. S. Vlasenko, H. Tanaka +5
Electron paramagnetic resonance of ensembles of phosphorus donors in silicon has been detected electrically with externally applied magnetic fields lower than 200 G. Because the sp…
Electrical injection and detection of spin-polarized electrons in silicon through an Fe_3Si/Si Schottky tunnel barrier
Y. Ando, K. Hamaya, K. Kasahara +5
We demonstrate electrical injection and detection of spin-polarized electrons in silicon (Si) using epitaxially grown Fe_3Si/Si Schottky-tunnel-barrier contacts. By an insertion of…
Insulating Phases Induced by Crossing of Partially Filled Landau Levels in a Si Quantum Well
Tohru Okamoto, Kohei Sasaki, Kiyohiko Toyama +3
We study magnetotransport in a high mobility Si two-dimensional electron system by in situ tilting of the sample relative to the magnetic field. A pronounced dip in the longitudina…
