1. What controls the Nanowire diameter ?Seed particle size / volume can be considered as a major factor irresponsible the Nanowire growth in conjunction with super saturation which is considered as a major factor controlling the Nanowire growth. Seed particle in most of the cases is a catalyst, e.g. Au. Sung Keun Lim et al 3 related mathematically the Nanowire diameter with the volume of ejaculate particle and parameter of import () which is the Particle-Nanowire contact angle. These authors 3 made use of two different precursors (group III and group V) one soluble in the seed and other insoluble in the seed particle which in this case is Au. They proposed a mechanics that controls the Nanowire diameter and this mechanism is based on the diffusion (or more precisely dissolution) of the soluble precursor in to the seed particle and further reaction with the insoluble precursorIf we operate at the steady state in such case Nanowire diameter frame constant because the rate of inject ion of soluble precursor into the seed and rate of further reaction with insoluble precursor are exactly t...
