Photoemission studies of quasicrystals

The results of the photoemission spectroscopy studies of the electronic structure of quasicrystals are reviewed. The presence and location of the features in the measured valence bands are in accordance with those in the calculated density of states. The existence of the theoretically predicted pseudogap at the Fermi level is confirmed. No evidence of the theoretically predicted spikiness of the density of states could be observed in the photoemission experiments of the highest energy resolution presently achievable.
