www.tyndall.ie Nanofabrication: ultra-thin films R. Feynman, Theres plenty of room at the bottom (1959): What could we do with layered structures with just the right layers? What would the properties of materials be if we could really arrange the atoms the way we want them? … When we have some control of the arrangement of things on a small scale we will get an enormously greater range of possible properties that substances can have, and of different things that we can do. Atomic layer deposition (ALD) has emerged as the processing technology of choice for high-quality films in demanding nanoscale geometries. R. Feynman, 29 Dec 1959, Annual Meeting of the American Physical Society at the California Institute of Technology; © Engineering and Science, Caltech; see http://www.zyvex.com/nanotech/feynman.html.
