Use of semiconductor technology has allowed investigation of quantum effects which occur when electrons are confined in dimensions less than three. When the size of the system is less than the scattering mean free path then wave function coherence dominates the transport properties giving rise to macroscopic quantum phenomena such as the conductance taking values ne2/h where n is an integer and e is the fundamental electron charge, h is Planck’s constant. This effect and a number of other quantum properties will be discussed.
