摘要

要讨论铁电向列液晶的界面取向，估算表面极性锚定能至关重要。在这项研究中，我们利用在测量普通向列液晶扭转角方面具有丰富经验的重归一化透射光谱椭偏仪，准确地估算了具有反平行摩擦方式的-扭转晶胞的扭转角。我们还成功地从简化扭矩平衡方程导出的基本方程中估算出了还原极性锚定能。假定还原表面极性锚定能量约为 102。

Evaluation of polar alignment structure and surface anchoring energy in ferroelectric nematic liquid crystals by renormalized transmission spectroscopic ellipsometry

It is essential to estimate the surface polar anchoring energy in order to discuss the interfacial orientation of ferroelectric nematic liquid crystals. In this study, we accurately estimated the twist angle of a -twist cell with an antiparallel rubbing manner, by means of renormalized transmission spectroscopic ellipsometry, which has a great deal of experience in measuring the twist angle of ordinary nematic liquid crystals. We also succeeded in estimating the reduced polar anchoring energy from the essential equation derived from the simplified torque balance equation. It is assumed that the reduced surface polar anchoring energy is on the order of 102.
