摘要：
We use a Landau-de Gennes model to study the effect of static external electric fields on the director and layer structure and switching in surface stabilized smectic-C cells with uniform chevron structure. We consider uniform switching of the whole cell and find the threshold electric field needed to switch the director from one stable state to the other stable state. The effect of temperature and cell thickness on the value of the threshold electric field is studied. We also find the switching time as a function of the strength of the applied electric field and study the director and layer structure during the switch.
