| Abstract: | Scanning tunneling spectroscopy measurements of Pb islands on Si(111) at high energy resolution reveal a novel pseudogap, or a pseudopeak in special cases, around the Fermi level in addition to the usual quantum well states. These gap or peak features persist to temperatures as high as ~80 K and are uniquely related to the quantum well nanostructure of the Pb islands. A systematic analysis indicates that electronphonon scattering is responsible for the observed electronic structure. |
