  11. Electrons in Two Dimensions: Quantum Corrals and Semiconductor Microstructures

    04 Dec 2007 | | Contributor(s):: Eric J. Heller

    The images generated by a scanning tunneling microscope are iconic. Some of the most famous are Don Eigler’s quantum corrals, which reveal not only the guest atoms on a surface but especially the interference patterns of electrons shuttling back and forth along the surface. To understand the...
