Abstract

The combination of lateral patterning techniques with refined molecular beam epitaxy methods will give considerable opportunities for the fabrication and study of extended nanostructures in the coming decade. A first target will be the understanding and exploitation of a host of quantum transport phenomena discovered in the last few years. The prospect of practicable quantum devices and circuits which utilise the coherent wave properties of the electron remains problematic but a range of new devices which exploit the Coulomb blockade is under investigation. The latter hold promise for high temperature operation and strong immunity against quantum fluctuations. The next decade should see the first exploration of the granular electronic limit in which one carrier might be expected to represent one bit of information. The granular electronic regime will provide an important arena for the resolution of fundamental controversies in quantum mechanics.
