Patent ID: 8524527

Claim:
A method of fabricating n-type dopant-doped metal oxide nanowires, comprising: dispersing nanoparticle catalysts on a Si/SiO 2 substrate; and growing n-type dopant-doped metal oxide nanowires on the Si/SiO 2 substrate using a laser ablation process, comprising: placing n-type dopant at an upper stream of a furnace, placing the Si/SiO 2 substrate at a downstream end of the furnace, heating the furnace, adding hydrogen to a carrier gas comprising argon and oxygen, flowing the hydrogen-added carrier gas over the Si/SiO 2 substrate to suppress oxidation processes and incorporate the n-type dopant into the metal oxide nanowires, and cooling the n-type dopant-doped metal oxide nanowires grown on the Si/SiO 2 substrate.
