摘要：
We present detailed ab initio calculations of the electronic structure in decagonal quasicrystals and approximants and in crystalline compounds in the Al-Cu-Co and Al-Mn systems. The observed anisotropy of the electronic structure is discussed in relation to the anomalous transport properties of the decagonal quasicrystals. Our results can explain the appearance of large transport anisotropies in the quasicrystalline and approximant phases. The effect of disorder on the anisotropies has been investigated.
