Definitions
- the invention relates to a method for producing a nanoelement field effect transistor, a nanoelement field effect transistor and a nanoelement arrangement.
- Nanostructures such as, for example, nanotubes, in particular carbon nanotubes, and nanorods, also called nanowires, are known as a possible successor to conventional semiconductor electronics.
- a carbon nanotube is a single-walled or multi-walled, tubular carbon compound.
- multi-walled nanotubes at least one inner nanotube is coaxially surrounded by an outer nanotube.
- Single-walled nanotubes typically have a diameter of one nanometer, the length of a nanotube may be several hundred microns. The ends of a nanotube are often completed with half a fullerene molecule each.
- CNT carbon nanotube field effect transistor
