Abstract:
1. A method of making a monolithic elongated nanowire, comprising the steps of: a. applying a mask polymer layer to a selected crystal surface of a seed crystal; b. defining a plurality of spaced apart elongated openings through the mask polymer layer, thereby exposing a corresponding plurality of portions of the crystal surface, the openings disposed so as to be aligned with and parallel to a selected crystal axis of the seed crystal; and c. subjecting the portions of the crystal surface to a chemical nutrient environment that causes crystalline material to grow from the plurality of portions for at least a period of time so that monocrystalline members grow from the elongated openings and until the monocrystalline members laterally expand so that each monocrystalline member grows into and merges with an adjacent one of the monocrystalline members, thereby forming a monolithic elongated nanowire.
