  • Abstract
    We study THz radiation from magneto-optically induced ultrafast currents in GaAs. Magnetic field and excitation intensity are found to have a distinct influence on the shape of the THz traces. The results suggest that these currents are an appropriate tool to investigate k-space carrier dynamics in semiconductors.
