十次对称准晶的光电导率

Optical conductivity of decagonal quasicrystals

讨论了十次对称准晶的光电导率,推导了十次对称准晶在周期方向和准周期平面不同的光电导率的计算公式,并以此计算了十次对称准晶AlCoCu的光电导率,得到了与实验值相当符合的结果.

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.
