Abstract
We use Landau - de Gennes model to find the minimum width of a switched str ipe in a surface stabilized smectic-C cell. The dependence of the critical width on temperature and on values of the nematic and smectic elastic const ants is estimated analytically. The results are compared with numerically o btained critical widths. We also find characteristic times in which the wal l between two switched regions is formed.
