- 論文の詳細を見る
Azimuthal anchoring energy was measured by a novel method for sample cells of several liquid crystals on various aligning layers. In this method, the deviation of director was measured and determined accurately, even in the case where the dispersion of the rotatory power is significant. The obtained azimuthal anchoring energy is widely distributed from 10^<-10> J/m^2 to 10^<-5> J/m^2 for samples with a pretilt angle ranging from 1.6 to 87.2 degrees. The azimuthal anchoring energy tends to depend on pretilt angles with even cosine powers. The experimental results can be theoretically explained by expanding the surface energy in power series of the tensor order parameter at the surface, the easy axis, and the surface normal unit vector.
