WebWe have studied the luminescence of narrow quantum wires at photoexcitation densities of up to 3 3 106 cm21. We show that even at these densities, which are well above the expected Mott density of 8 3 105 cm21, excitonic recombination dominates over other recombination channels in stark contrast with the behavior of quantum wells and bulk … WebThe opportunity to form one-dimensional (1D) materials and devices via epitaxially nucleated growth of whiskers was realized more than 30 years ago by Wagner and others [1]. At that time, technology as well as the general awareness of the technology on small length-scales only permitted whisker dimensions typically down to the micrometer region. In mesoscopic physics, a quantum wire is an electrically conducting wire in which quantum effects influence the transport properties. Usually such effects appear in the dimension of nanometers, so they are also referred to as nanowires.
