Abstract

In quantum wires, ultranarrow conduction channels having very low disorder, electrons can scatter from potentials which are radically different from those encountered in the bulk. Entirely new types of scattering potentials can be created by microfabrication, since ballistic devices having overall dimensions much smaller than the transport mean free path, and widths only slightly larger than one electron wavelength, can now be fabricated.1
