Physical Review Letters 55, no. 9: 987-990. doi:10.1103/physrevlett.55.987.0031-9007http://nrs.harvard.edu/urn-3:HUL.InstRepos:29407045Electron standing waves formed in the vacuum gap between the probe and the sample of the tunneling microscope are observed. The sensitivity of the standing-wave positions and frequencies to the surface potential are demonstrated. Further effects possibly due to Bragg backscattering from the surface atomic planes of the sample are discussed.en-USJournal Article2016-11-1810.1103/PhysRevLett.55.987
