nanotechnology

Physics
  • The development and use of devices that have a size of only a few nanometres. Research has been carried out into very small components, which depend on electronic effects and may involve movement of a countable number of electrons in their action. Such devices would act much faster than larger components. Considerable interest has been shown in the production of structures on a molecular level by suitable sequences of chemical reactions. It is also possible to manipulate individual atoms on surfaces. See also Nanophysics (Feature).


Chemistry
  • The development and use of devices that have a size of only a few nanometres. Research has been carried out into very small components, which depend on electronic effects and may involve movement of a countable number of electrons in their action. Such devices would act much faster than larger components. Considerable interest has been shown in the production of structures on a molecular level by suitable sequences of chemical reactions. It is also possible to manipulate individual atoms on surfaces using a variant of the atomic force microscope.


Chemical Engineering
  • The study of materials of the nanometre scale ranging from 1 to 100 nm. Nanotechnology involves the creation and/or manipulation of nanomaterials, either by scaling up from single groups of atoms, or by refining or reducing bulk materials.


Electronics and Electrical Engineering
  • The construction and handling of nanostructures. Nanotechnology was predicted in 1959 by physicist Richard Feynman, but did not get under way until the invention of scanning-tunnelling microscopy in 1981. Today a range of nanofabrication techniques exist, using very high-resolution microscopes, lithography, chemical synthesis, and various self-assembly techniques. See also nanoelectronics.
