Notes:
We investigate how and to what extent the one-dimensional (1D) subband separation of V-groove GaAs/AlGaAs quantum wires (QWRs) can be tuned in a controlled way without compromising the wire uniformity and interface quality. Our results demonstrate that high quality V-groove QWRs with subbands separation up to ∼3kBTroom (ΔE=80 meV) can be obtained. The ratio between the subband separation and the inhomogeneous broadening of the QWRs emission line, extracted from low-temperature photoluminescence and photoluminescence excitation spectra, is as large as 7.1. Finally, we show that the 1D features in the optical spectra are maintained up to 300 K, making these QWRs suitable for room temperature device application. © 2002 American Institute of Physics.
