摘要：

The recombination kinetics of the quasi-one-dimensional (1D) carriers confined in quantum wires grown by organometallic chemical vapor deposition on nonplanar, patterned substrates is reported for the first time. Due to the small (240 nm) wire spacing, excited carriers are efficiently captured into the wires on a sub-ps time scale. The radiative recombination lifetime of the captured 1D carriers is longer than 310 ps. Time-resolved cathodoluminescence spectra directly monitor thermalization of the carriers within the wire.
