Optical conductivity of decagonal quasicrystals
十次对称准晶的光电导率

A disscussion is given of the optical conductivity of decagonal quasicrystals. With group theory it is proved that decagonal quasicrystals may have different optical conductivity in the periodic and quasiperiodic directions. The formula is derived for the optical conductivity. The optical conductivity of Al65Co17 Cu18 is calculated using this formula. The calculated results basically agree with the experimental data.
