Embodiment Construction
[0025] Nanowires are generally interpreted as nanostructures whose diameters are nanometer-sized. As the term "nanowire" implies, its lateral dimensions are on the order of nanometers and its longitudinal dimensions are unlimited. Such nanostructures are also commonly referred to as nanowhiskers, one-dimensional nanocomponents, nanorods, and the like. Although these terms imply an elongated shape, the nanowires may be tapered or stub-like, and since nanowires may have a variety of cross-sectional shapes, in this application the diameter is intended to mean effective diameter. Generally, nanowires are considered to have at least two dimensions, each no larger than 300 nm, but nanowires may have a diameter or width of up to about 1 um. The one-dimensional nature of the nanowires provides unique physical, optical and electronic properties. These properties can be used, for example, to form devices that exploit quantum mechanical effects or to form heterostructures of compositi...
