In this paper, a 1.8 keV ion beam (IB) sputtered thin layer of aluminum-doped zinc oxide (AZO) with columnar AZO bumps covering the surface working as an alignment layer for the homogeneous alignment of liquid crystals (LC) is investigated. Bumpy AZO alignment layers in twisted nematic (TN) cells generated larger LC pre-tilt angles and thus enabled accelerated switching of LC, and the highly conductive bumpy AZO thin layers allowed super-fast release of accumulated charges, and led to low residual DC performance. These results indicate the promising applications of AZO bumps layer as alignment layer in LC devices.
本文研究了用1.8 keV离子束（IB）溅射的掺铝氧化锌（AZO）薄层，其表面覆盖有柱状AZO凸起，用作液晶（LC）均匀取向的取向层。扭曲向列（TN）单元中的凹凸AZO取向层产生了更大的液晶预倾角，从而实现了液晶的加速切换，并且高导电性的凹凸AZO薄层允许快速释放积累的电荷，并导致低残余直流性能。这些结果表明AZO凸起层作为液晶器件取向层具有广阔的应用前景。
