Electronic states of moiré modulated Cu films

We examined by low-energy electron diffraction (fig 1b) and scanning tunneling microscopy (fig 1a) the surface of thin Cu Figure - 2 films on Pt(111). The Cu/Pt lattice mismatch induces a moiré modulation (fig 1c) for films from 3 to about 10 ML thickness. We used angle-resolved photoemission spectroscopy to examine the effects of this structural modulation on the electronic states of the system. A series of hexagonal- and t rigonal-like constant energy contours is found in the proximity of the Cu(111) zone boundaries (fig 2a, 2b). These electronic patterns are generated by Cu sp-quantum well state replicas, originating from multiple points of the reciprocal lattice associated with the moiré superstructure, which is also shown by calculation (fig 2c, 2d).
