- 論文の詳細を見る
Measurements with photoemission spectroscopy in the photonenergy range 35-150 eV have been used to measure the valence band of the stable icosahedral Al_<70>Pd_<20>Mn_<10>. The maxima of the Pd 4d- and Mn 3d derived states are respectively at 3.6 and 0.7 eV below the Fermi level. The strong decrease of intensity towards the Fermi level is interpreted as evidence for the presence of a pseudogap at the Fermi level. No unusual features in the valence band of icosahedral Al_<70>Pd_<20>Mn_<10>, which could be ascribed to its quasiperiodic nature, are observed within the resolution of the experiment.icosahedral alloyphotoemissionelectronic stateFermi level
