Title: Flexoelectricity in nematic domain walls. Author: Elston SJ. Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2008 Jul; 78(1 Pt 1):011701. PubMed ID: 18763967. Abstract: Flexoelectric effects are studied in the domain walls of a nematic liquid crystal device showing the Freedericksz transition. Walls parallel to the alignment direction have a strong twist distortion and an electro-optic effect dominated by e1-e3 is seen. Walls perpendicular to the alignment direction have a strong splay-bend distortion and an electro-optic effect dominated by e1+e3 is seen. This allows the study of both flexoelectric coefficient combinations in a single device.[Abstract] [Full Text] [Related] [New Search]
