Abstract
Differently prepared surfaces of quasicrystalline i-Al-Pd-Mn are analyzed u sing angle-resolved photoemission in the x-ray and ultraviolet range of pho ton energies. Depending on the preparation, we find both surfaces with crys talline structure and metallic character, and surfaces with quasicrystallin e structural fingerprints and a suppressed density of states at the Fermi l evel, compatible with a pseudogap.
