Image of FIG. 1.
FIG. 1.

Illustration of the surface stabilized ferroelectric liquid crystal layer geometry. The chevron structure, layer tilt angle , and smectic cone angle are depicted in the side view (a). End views are shown for the cases where the azimuthal angle at the surfaces, , were as follows: (b) , (c) , (d) , and (e) .

FIG. 2.

Time–voltage switching curve (taken from Ref. 9). Curve (a), closed circles, shows a single minimum and corresponds to a rubbed nylon alignment layer. Curve (b), open circles, shows two minima with a sharp cusp between them. This was observed for the same material but with a polyimide alignment layer.

Image of FIG. 3.
FIG. 3.

Time–volatge switching curves generated by the continuum simulation with the parameters from Table I for the geometries shown in Fig. 1. Values for are shown next to the appropriate curve.

Image of FIG. 4.
FIG. 4.

Time–voltage switching curves generated by the continuum simulation for the geometries shown in Fig. 1 with . The parameters from Table I were used except for the dielectric biaxiality which was varied between (lower curve) and (upper curve) as indicated.

Tables

Table I.

Values used for the dielectric, elastic, and physical parameters of the smectic liquid crystal in the numerical simulations.
