摘要
In accordance with the 2D Landau-de Gennes tensorial formalism, we investigated the influence of an applied electric field E parallel to the defect line on the position and structure of a nematic line defect with topological charge M = -1/2 in a hybrid alignment nematic cell with different cell gaps d. A new type of surface order reconstruction occurs in the cell as E is increased. Regardless of d, two biaxial layers can be achieved near the top and bottom substrates of the cell with different E values. This process involves double eigenvalue exchange across the cell. However, the structural transition processes vary for different d values.
