Patent ID: 7453097

Claim:
A nanowire light emitting device comprising: a substrate; a first conductive layer formed on the substrate; a plurality of nanowires vertically formed on the first conductive layer, each nanowire having a p-type doped portion and an n-type doped portion separately; a light emitting layer between the p-type doped portion and the n-type doped portion; a second conductive layer formed on the nanowires; and an insulating polymer, not containing dopant ions, filling a space between the nanowires on the first conductive layer; wherein the n-type doped portion includes a portion including molecules having a low ionization potential, wherein the p-type doped portion includes a portion including molecules having a high electron affinity, wherein the molecules having the high electron affinity contain fluorine, wherein the molecules having a low ionization potential are molecules containing at least one metal selected from the group consisting of lithium, copper, and zinc, or organic molecules.
