Surface electron motion near monatomic steps: Two-photon photoemission studies on stepped Cu(111)

Abstract: The electronic structure of three surface or near-surface states on stepped Cu͑775͒ has been investigated using angle-resolved, resonant, two-photon photoemission. Since the electron wave function in each of these electronic states has a different average distance from the crystal plane, the measurement allowed the step potential at each distance to be sampled. The energy dispersion of the nϭ1 image-potential state was found to be oriented by the ͑111͒ terrace and the nϭ2 state was oriented by the ͑775͒ surfac… Show more

“…Angle-resolved photoemission data, on the other hand, produce E͑k͒ band dispersions that lead to the picture in Fig. 1(a) [8][9][10]. In addition, backfolding of the surface state band by the reciprocal vector of the step superlattice has been reported and explained in a model consistent with Fig.…”

“…In contrast, in STM a single terrace is enough to study electronic properties, such as confinement or scattering, but the reciprocal space of the superlattice cannot be properly investigated as in photoemission. It is interesting to note the difference between STM experiments that reveal total electron confinement [4,5], and photoemission results that show electron dispersion across the steps and superlattice effects [3,6,7]. Although the differences appear to be related to the average terrace size involved (large in STM, small in photoemission, [3]), in fact terrace confinement of surface states observed with photoemission has never been reported previously.…”
