Abstract

Abstract: We investigated homogeneous liquid crystal alignment on hafnium strontium oxide films deposited by a solution process, where the liquid crystal alignment was induced by ion-beam irradiation. Uniform liquid crystal alignment was achieved on the HfSrO films grown at 300 °C. We confirmed the effect of surface morphology and chemical composition of HfSrO films using field-emission scanning electron microscopy and X-ray photoelectron spectroscopy. In addition, we observed the electro-optical characteristics of the twisted-nematic liquid crystal cells based on hafnium strontium oxide films to verify the possibility of their application in liquid crystal displays.
