AI Article Synopsis
- Flexoelectric effects in nematic liquid crystal devices are explored through the behavior of domain walls during the Freedericksz transition.
- Domain walls that are parallel to the alignment direction exhibit significant twist distortion and an electro-optic effect primarily influenced by the combination of coefficients e1-e3.
- Conversely, walls perpendicular to the alignment direction show strong splay-bend distortion with an electro-optic effect led by the combination e1+e3, facilitating the analysis of both types of flexoelectric coefficients in one device.
Article 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.
