摘要：

Quasi-one-dimensional carrier transport is studied in a single AlxGa1-xAs/GaAs quantum wire by combining two-color femtosecond pump and probe spectroscopy and near-field optical microscopy. Evidence is found for a transient nonambipolar electron transport along the wire axis on a picosecond time and 100 nanometer length scale.
