Ultrafast Spin Phenomena in Highly Excited N-Doped GaAs



R Bratschitsch, Z Chen, Steven T. Cundiff


We perform time-resolved Faraday rotation exeriments on undoped and n-doped GaAs samples at high optical excitation densities. The Faraday rotation signal linearly increases with optical excitation density. The excitation dependence of the electron g-factor shows that many-body effects strongly affect spin phenomena in semiconductors.
