Hello,

There are many methods to produce artificial or custom nanostructures, this in general depends on: 1. Type of Material desired (e.g. nanoparticle, nanowire or a quantum dot) 2. Desired property of the structure (e.g. size, uniformity, surface roughness) 3. The number of structures/particles needed

If I’m not mistaken, what you like to know is concerning both nanomaterials and nanostructures.

Nanomaterials: They often refer to Nanoparticles, which are produced by various methods. This process is often referred to as Growth/Synthesis. I can not elaborate much on this, as it is more related to Materials Science/Chemistry. Nanoparticles can be embedded within Nanostructures (e.g. Metallic Nanoparticles in Solar Cell, to benefit from the Plasmonic enhancement to effectively absorb more light). Carbon Nanotubes are also included within this category. Widely used materials in this category: Gold Nanoparticles and others. NanoStructures: They refer to patterned structures made with various techniques often to produce semiconductor devices (or so called sub-micron electronics = nanoelectronics). The methods used here are:
