Abstract

Nematic liquid crystal alignment capabilities and electro-optical performance characteristics have first been embodied in a ZrO2 layer using ion-beam irradiation. The study demonstrates that liquid crystal layers can be aligned homogeneously as a function of the incident angle of the ion beam device, which causes a uniform dense plasma. X-ray photoelectron spectroscopy indicated that full oxidation of the ZrO2 thin-film surfaces was produced by ion irradiation, shifting the Zr 3d spectra to lower binding energies. In addition, the electro-optical performance characteristics of twisted nematic cells on a ZrO2 thin-film layer after ion beam irradiation showed similar characteristics to those of a rubbed polyimide cell.
