Detailed explanation-1: -Carbon nanotubes (CNT) are a tube made of carbon with diameters usually measured in nanometers. If a material has two dimensions outside the nanoscale and only one dimension with one thickness or a few atomic layers, then these nanomaterials are classified as two-dimensional (2D) nanomaterials.
Detailed explanation-2: -Two-dimensional (2D) nanomaterials are composed of thin layers that may have a thickness of at least one atomic layer. Contrary to bulk materials, these nanomaterials have a high aspect ratio (surface-area-to-volume ratio) and therefore have many atoms on their surface.
Detailed explanation-3: -Flexible Field Emitters Based On Other Materials One-dimensional (1D) nanostructures with a high aspect ratio, such as nanotubes and nanowires, have been considered to be ideal field emitters that can emit electrons in a low electric field.
Detailed explanation-4: -Carbon nanoscale building block regimes mainly contain zero-dimensional (0D) nanodots, one-dimensional (1D) nanotubes, two-dimensional (2D) graphene, and their derivatives5, 6.
