Imaging Coherent Electron Flow (Westervelt, Gossard, Heller) Scanning probe microscopy of electron flow using a capacitively-coupled tip. Images of electron flow through the first three modes of a quantum point contact in a 2D electron gas; expt outside, theory inside; fringes spaced by 1/2 Fermi wavelength demonstrate coherence.
