Nematic director configurations in high pretilt, parallel aligned layers
We describe the director configurations associated with a negative dielectric anisotropy, high pretilt (typically ~ 85°) nematic cell. A number of distinct director configurations are observed, with both a transition to a spontaneously twisted state and a nucleated transition mediated by disclinatio...

| Summary: | We describe the director configurations associated with a negative dielectric anisotropy, high pretilt (typically ~ 85°) nematic cell. A number of distinct director configurations are observed, with both a transition to a spontaneously twisted state and a nucleated transition mediated by disclination line movement. We discuss the role of surface pretilt and elastic constant anisotropy on behaviour and give results on the relative energetic stability of the director states. |
