The term "nanotechnology" refers to the research being conducted in cluster physics and surface physics, surface chemistry, semiconductor physics, specific areas of chemistry and, to a more limited extent, in areas of mechanical engineering and food technology ("nano food"). The collective term is derived from the magnitude common to all of the research areas, namely, structures with sizes ranging from a single atom to 100 nanometers (nm). Nanomaterials play an increasingly important role in the miniaturization of circuit elements. Typical modern representatives of nanotech products are the so-called "quantum dots". Modern processors also have structures smaller than 100 nm, which could therefore also be called "nanotech" as well.
