ABSTRACT This work shows the doping effect of metal oxide nanowires (alumina nanowires) on the textural and electro-optical characteristics of nematic liquid crystal (5CB) in planar and in-plane switching (IPS) cell configurations. Results indicate the increase in nematic to isotropic phase transition temperature after doping in both planar and IPS cells. A decrease in threshold voltage in addition to increase in contrast ratio, birefringence, and band gap energy was observed after doping with alumina nanowires in both types of cells. Overall analysis shows that IPS cell configuration has more improved threshold voltage and contrast ratio in addition to decrease in birefringence and transmission intensity, as compared to planar cell configuration. No effect of cell configuration was observed on energy band gap and found same value for both planar and IPS cell configurations, as energy band gap is a material specific property.

在平面和平面开关单元配置中掺杂金属氧化物纳米线的室温向列液晶 4̍-pentyl-4-biphenylcarbonitrile 的结构和电光研究

摘要 这项工作显示了金属氧化物纳米线（氧化铝纳米线）对平面和面内切换 (IPS) 单元配置中的向列液晶 (5CB) 的纹理和电光特性的掺杂效应。结果表明在平面和 IPS 电池中掺杂后，向列到各向同性的相变温度增加。在两种类型的电池中掺杂氧化铝纳米线后，除了对比度、双折射和带隙能量的增加外，还观察到阈值电压的降低。总体分析表明，与平面单元配置相比，IPS 单元配置除了降低双折射和透射强度外，还具有更多的改善的阈值电压和对比度。没有观察到电池配置对能带隙的影响，并且发现平面和 IPS 电池配置的值相同，因为能带隙是材料特定的属性。图形概要
