Coherent Electron Flow
Caption:
This image shows the coherent flow of electrons through a quantum point contact. The contact is formed in a two-dimensional electron gas inside a GaAs/AlGaAs heterostructure. Scanned probe microscope images on the outside agree well with theoretical simulations inside. The fringes are spaced by half the electron wavelength.
This work was supported by a National Science Foundation grant.
