      abstract     = {We examined by low-energy electron diffraction and scanning
                      tunneling microscopy the surface of thin Cu films on
                      Pt(111). The Cu/Pt lattice mismatch induces a moiré
                      modulation 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
                      trigonal-like constant energy contours is found in the
                      proximity of the Cu(111) zone boundaries. 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. Layer-dependent
                      strain relaxation and hybridization with the substrate bands
                      concur to determine the dispersion and energy position of
                      the Cu Shockley surface state.},
