## Structure and electronic structure of quasicrystal and approximant surfaces: a photoemission study

### In: Progress in Surface Science, 2004, vol. 75, p. 205-225

The structure and electronic structure of different high-symmetry surfaces of either quasicrystalline or approximant Al–Pd–Mn were studied by means of photoemission-based techniques such as X-ray photoelectron diffraction (XPD) and ultraviolet photoelectron spectroscopy. We find that the twofold (2f), 3f and 5f surfaces of icosahedral Al–Pd–Mn exhibit all the symmetry elements of the... More
