Momentum Distribution of Valence Electrons in a Single Al-Li-Cu Icosahedral Quasicrystal

概要
- 論文の詳細を見る
A single Al_<59.3>Li_<29.3>Cu_<11.4> icosahedral quasicrystal is prepared with the Bridgman method. To study the electronic structure of this phase, high resolution Compton profiles along the axes of the five- and two-fold symmetries of the single quasicrystal phase have been measured with 60-keV synchrotron radiation X-rays. The Fermi cutoffs are observed clearly in the profiles. Anisotropy in the electron momentum distribution is not found. Although the valence electron profiles can be fitted with an inverted parabola, the free-electron model does not explain the shape of profiles and the momentum values of the Fermi cutoffs. Based on a concept of the quasi-Brillouin zone boundary the effects of strong electron-lattice interaction on the electron momentum distribution have been examined.
