The Propagation of disclinations in bistable switching

摘要

The boundaryhyphen;layer model is used to calculate the energy density of the forces that govern the movementhyphen;ofhyphen;strength 1/2 disclinations in a bistable tilted liquidhyphen;crystal geometry during switching. The distortions of the bistable states and the disclinations separating them are studied. The mobility is calculated for vertical and transverse applied fields and compared with experimental data, showing good agreement especially at high fields. Implications about a switching mechanism are discussed.
