Nanotechnology and Nanoelectronics “I can hardly doubt that 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.” – R. Feynman (1959) “The aim of electronics should be … to perform needed systems functions as directly, as simply, and as economically as possible from relevant knowledge of energy-matter interactions” – J. A. Morton (1965) 3
