Abstract:
1. A method for producing nanowires comprising the step of: forming a composite film, such that the composite film of at least two phases has at least one outwardly oriented surface, wherein a first phase is a metallic material, the metallic material including at least one of bismuth, indium, tin, lead, zinc, antimony, alloys containing bismuth, alloys containing indium, alloys containing tin, alloys containing lead, alloys containing zinc and alloys containing antimony, and a second phase functions as a host matrix, the composite film emitting nanowires composed of the metallic material of the first phase and having an elongated crystalline structure, a diameter less than about 500 nanometers and an aspect ratio of at least 100.
