A spin light emitting diode incorporating ability of electrical helicity switching
N. Nishizawa, K. Nishibayashi, H. Munekata
Fabrication and optical characteristics of a spin light-emitting-diode (spin-LED) having dual spin-injection electrodes with anti-parallel magnetization configuration are reported.…
Efficient spin injection through a crystalline AlOx tunnel barrier prepared by the oxidation of an ultra-thin Al epitaxial layer on GaAs
N. Nishizawa, H. Munekata
We report that an ultra-thin, post-oxidized aluminum epilayer grown on the AlGaAs surface works as a high-quality tunnel barrier for spin injection from a ferromagnetic metal to a…
Origin and control of high-temperature ferromagnetism in semiconductors
Shinji Kuroda, Nozomi Nishizawa, Koki Takita +4
The extensive experimental and computational search for multifunctional materials has resulted in the development of semiconductor and oxide systems, such as (Ga,Mn)N, (Zn,Cr)Te, a…
Significant enhancement of ferromagnetism in ZnCrTe doped with iodine as an n-type dopant
Nobuhiko Ozaki, Nozomi Nishizawa, Stephane Marcet +3
The effect of additional doping of charge impurities was investigated in a ferromagnetic semiconductor ZnCrTe. It was found that the doping of iodine, which is expect…
