Solution-Based Growth of Nanowires

This synthetic strategy for nanowires makes use of anisotropic growth dictated by the crystallographic structure of a solid material or confined and directed by templates or kinetically controlled by supersaturation or by the use of appropriate capping agents. 

Template-Based Synthesis Template directed synthesis represents a convenient and versatile method for generating ID nanostructures. In this technique, the 

The nanowires themselves can be used as templates to generate the nanowires of other materials. The template may be coated onto the nanowire (physically) forming coaxial nanocables [316a], or it may react with the nanowires forming a new material [317a,b]. In the physical (solution or sol-gel coating) approach, the surfaces of the nanowires could be directly coated with conformal sheaths made of a different material to form coaxial nanocables. Subsequent dissolution of the original nanowires could lead to nanotubes of the coated material. The sol-gel 

Solution-Liquid-Solid Process Buhro and coworkers [276], have developed a low temperature solution-liquid-solid (SLS) method for the synthesis of highly crystalline nanowires of III-V semiconductors [276, 327]. In a typical procedure, a metal (e.g., In, Sn, Bi) with a low melting point was used as a catalyst, and the de- 

In addition to these solution routes to elemental and III-V semiconductor nanowires, it has recently been reported that, by exploring the selective capping capabilities of mixed surfactants, it is now possible to extend the well-established
