This part will give an overview of nanomaterials - the production methods, their properties, brief examples of applications and demonstrations of their capabilities.
Apart from a general overview of production methods, we have divided the materials as
- Semiconducting
- Metallic
- Organic
A division that might be up for revision shortly.
|
One way to classify a material is its electronic structure |
Another is according to their geometry |
Overview of nanomaterials
| Type | Structure | Production | Properties | |
|---|---|---|---|---|
| Buckyballs/ C60 | ||||
| Single Wall Carbon Nanotubes (SWCNT) | Semiconducting or metallic depending on how the carbon lattice is twisted. | |||
| Multi Wall Carbon Nanotubes (MWCNT) | Concentric shells of SWCNT, diameter up to hundreds of nm | |||
| Silicon Nanowires and heterostructures | Silicon crystals with diameters from a few nm | Typically VLS growth | ||
| III-V Nanowires | crystals with diameters from a few nm | typically VLS growth. A wealth of heterostructures can be formed to make tunnel barrier junctions etc. | Semiconducting, often optically active and fluorescing due to direct bandgap (unlike silicon). | |
| Gold nanoparticles | ||||
| Silica nanoparticles | ||||
| Platinum nanoparticles | small metallic clusters | Used as catalysts in many reactions |
