Abstract:
1. A nanowire light emitting device comprising: a substrate; a first conductive layer disposed on the substrate; a plurality of nanowires vertically disposed on the first conductive layer, each nanowire comprising a p-doped portion and an n-doped portion; a light emitting layer between the p-doped portion and the n-doped portion; a second conductive layer disposed on the nanowires; and an insulating polymer in which a light emitting material is embedded, filling a space between the nanowires, wherein a color of light emitted from the light emitting layer varies according to the light emitting material, wherein the p-doped portion of the nanowires comprises a first plurality of molecules having a high electron affinity which are adsorbed on the p-doped portion, wherein the first plurality of the molecules comprise fluorine, and wherein the n-doped portion of the nanowires comprises a second plurality of molecules having a low ionization potential which are adsorbed on the n-doped portion, wherein the second plurality of the molecules comprise organic electron donor molecules or molecules containing at least one metal selected from the group consisting of lithium, copper, and zinc.
