Abstract

In recent years semiconductor nanostructures have become the model system of choice for investigations of electrical conductivity on short length scales.^[2] These developments were made possible by the availability of semiconductor materials of unprecedented purity and crystalline perfection. In these materials the old dream of observing the effects of the motion of a single electron without any other influences but only that of the walls and the external forces can be achieved as K. Leo et.al.^[3] have recently demonstrated. Recently we presented findings^[1,4] on some aspects of electron tunnelling dynamics which might have considerable relevance to some issues in the current literature. We believe that theses neglected properties might be of importance to recent experiments of time development of wave packets in real or configuration coordinate space in atoms, molecules and solids as in driven nonlinear systems which exhibit Classical Chaos.^[5]
