Nanodiamonds indicate synthetic diamond materials that have sizes or feature sizes (e.g., grain sizes) between 1 and lOOnm, generally including two forms particulate and thin film. Because the nanodiamond thin film is actually composed of nanosized columnar crystals or grains, the material is also known as nanocrystalline diamond. Due to its close relationship and similarity to nanodiamonds, nanostructured diamondlike carbon has also attracted considerable attention. In the following sections, these carbon nanostructures are discussed separately.
