Electron Coherence in a Melting Lead Monolayer (Science 306 (2004) 2221. download (0.5 MB))



Evolution of the Fermi surface through the melting transition of lead on a copper single crystal. Melting of the Pb layer occurs between
553 K and 585 K. Note that the copper Fermi surface contours remain sharp throughout the melting transition of the film. The dominant
Pb and Cu contours are traced by the solid and dashed white lines, respectively.
