On NaCl(100)/Cu(111) an interface state band is observed that descends fromthe surface-state band of the clean copper surface. This band exhibits aMoire-pattern-induced one-dimensional band gap, which is accompanied by strongstanding-wave patterns, as revealed in low-temperature scanning tunnelingmicroscopy images. At NaCl island step edges, one can directly see therefraction of these standing waves, which obey Snell's refraction law.Comment: 4 pages, 4 figure
