| Abstract: | The influence of the finite dimension of a chiral smectic C liquid crystal planar sample on the helical pitch length is discussed. The discussion is based on the properties of the disclination PH2 system described in Czech. J. Phys. B35 (1985) 655. It is concluded that the existence of the sample free surface can lead to pitch changes with respect to the pitch of a perfect infinite chiral smectic C liquid crystal. |
