  • Abstract
    We demonstrate all-optically induced real-space charge transfer in semiconductors, which reverses its direction upon a change of the temporal order of two excitation fields. Such charge transfer leads to a new type of photocurrent and only appears for certain polarization-shaped optical pulses while it ceases for continuous-wave excitation.
