Morphology of SiO(2) films as a key factor in alignment of liquid crystals with negative dielectric anisotropy

Control of liquid crystal (LC) orientation using a proper SiO(2) alignment layer is essential for the optimization of vertically aligned nematic (VAN) displays. With this aim, we studied the optical anisotropy of thin SiO(2) films by generalized ellipsometry as a function of deposition angle. The co...

description Control of liquid crystal (LC) orientation using a proper SiO(2) alignment layer is essential for the optimization of vertically aligned nematic (VAN) displays. With this aim, we studied the optical anisotropy of thin SiO(2) films by generalized ellipsometry as a function of deposition angle. The columnar SiO(2) structure orientation measured by a noninvasive ellipsometry technique is reported for the first time, and its morphology influence on the LC alignment is demonstrated for large deposition angles.
