Optical Spin Injection in Silicon — •Eduard Sauter — Abt. Nanostrukturen Leibniz Universitaet Hannover

Silicon is a promising candidate for electron spin manipulation due to lack of nuclear spin of the 28 isotope and low spin orbit coupling due to inversion symmetry of the unit cell. I would like to present results of electron spin manipulation by circularly polarized light with energy close to the band gap in the NIR region. The observed decay of spin orientation with increasing magnetic field is an indicator for the spin lifetime of electrons.
