Abstract:
1. A method of fabricating a set of semiconducting nanowires having a desired wire diameter, the method comprising the acts of: providing a set of pre-fabricated semiconducting nanowires, at least one pre-fabricated semiconducting nanowire having a wire diameter larger than the desired wire diameter; reducing the wire diameter of the at least one pre-fabricated nanowire by etching, the etching being induced by electromagnetic radiation which is absorbed by the at least one pre-fabricated nanowire; selecting a minimum wavelength of the electromagnetic radiation such that the absorption of the at least one pre-fabricated nanowire is significantly reduced when the at least one pre-fabricated nanowire reaches the desired wire diameter; and stopping the electromagnetic radiation when continuing the electromagnetic radiation does not substantially change the desired wire diameter.
