We use scanning tunneling spectroscopy (STS) to investigate the electronic structures of dense Pb overlayers of three phases grown on the Si(111) surface: the 1 ×1, √7 ×√3, and stripe incommensurate (SIC) phases. Although their atomic structures are all very different, the STS spectra of all three p...
