... the initial direct excited states (C points in the first Brillouin zone) to the surface-related states surrounding the core of Si-NCs. The relaxation of carriers within the surface-related states (*5 ... surface-related states surrounding the core of NCs, which inhibit the Auger recombination. The fast transfer of carriers to these states (*1 ps) minimizes the probability for these...

... armchair tubes it is a singlet. In the zig-zag tubes the density of states at the Fermi level is greater for the spin down states compared to the spin up state indicating that the doped tubes ... rolled into tubes which can be microns in length and have diameters from 5 A to 20 A. The tubes may be metal, insulating or semi- conducting depending on their chirality. There is much intere...
