Abstract:
1. A method of fabricating a nanowire, comprising the steps of: (a) positioning a substrate over a support structure such that a part of the substrate is not supported by the support structure and is suspended over the support structure; (b) depositing a semiconductor oxide film over the substrate; (c) depositing an indium oxide film, which is optically transparent and electrically insulating, over the semiconductor oxide film; (d) depositing an anti-charging film over the indium oxide film such that a layered structure is formed with the anti-charging film as the top layer; (e) focusing and projecting a beam of Ga ions onto the anti-charging film over a region corresponding to the suspended part of the substrate to implant Ga ions into the indium oxide film; and (f) immediately removing the top layer from the layered structure after step (e) such that a surface of the indium oxide film with at least one Ga-doped nanowire is exposed.
