Ultrafast laser induced nanostructured ITO for liquid crystal alignment and higher transparency electrodes

摘要: Femtosecond laser nanostructured indium tin oxide (ITO) coated glass is shown to act both as a liquid crystal (LC) alignment layer and an electrode with higher transparency. The nanopatterns of the 120 nm period were created using ultrashort pulses directly on ITO films without any additional spin coating materials or lithography process. Nine regions laser-induced nanostructures fabricated different orientations various pulse energy levels top confirming follow-up LC director line orientation. device interfacial anchoring was found be ∼ 1 μ J / m 2, comparable nematic photosensitive polymers. transparency improve due better antireflection lower absorption expected from surface.Femtosecond surface.
