Spatially Indirect Optical Transitions in Semiconductor Multiple Quantum Wires
Published online by Cambridge University Press: 28 February 2011
Abstract
In optical experiments with laterally patterned modulation-doped GaAs/AlGaAs quantum wells we observe spatially separate confinement of electrons and holes to one-dimensional quantum wires. We determine the one-dimensional subband spacing and Fermi energy from inelastic light scattering and photoluminescence spectra. From these measurements we directly determine the one-dimensional electron density.
