Properties of Spatially Indirect Excitons in Nanowire Arrays
This paper deals with the excitons formed by electrons and holes located in different, closely placed semiconducting nanowires (spatially indirect excitons). We calculated the charge densities and the binding energies of the excitons for different nanowire diameters <i>D</i> and distance...

| description | This paper deals with the excitons formed by electrons and holes located in different, closely placed semiconducting nanowires (spatially indirect excitons). We calculated the charge densities and the binding energies of the excitons for different nanowire diameters <i>D</i> and distances <i>h</i> between the nanowires. Together with the estimated exciton lifetimes, these results suggest that at certain <i>h</i> and <i>D,</i> the spatially indirect excitons in the nanowire arrays may have the potential to serve as information-processing units. Possible ways of exciton generation in the nanowire arrays are discussed. |
