摘要：

We report a study of the temporal evolution of the luminescence from an electron-hole plasma confined in GaAs quantum wires under high-power excitation. In the spectra 1 D intersubband transitions with quantum numbers as high as n = 5 are resolved. The spectral positions are in excellent agreement with Kohn-Luttinger calculations based on an active wire width of w = 60 +/- 5 nm, accurately determined by an x-ray-diffraction method employed for 1 D systems. The decay of the luminescence and the hot-carrier cooling rate, which is obtained from line-shape analysis, are found to be slower than the corresponding processes in quantum wells.
