| 抄録: | We report coherently controlled photocurrent at room temperature in subpicosecond dynamics. The photocurrent intensity shows a periodic change depending on the time interval between the phase-locked pulses. We identify the carrier generation due to shallow acceptors in bulk GaAs by measuring the photocurrent beat period. The non-instantaneous photocurrent beat expresses the ultrafast coherent dynamics, including the dephasing process of the photogenerated carriers. We also demonstrate photocurrent direction control through manipulation of the localized states. |
