N2 - The effect of surfaces on the stability of smectic- C* (Sm C*) variant phases is investigated. The results obtained using dielectric spectroscopy by varying the cell thickness show that the temperature ranges of Sm Cα*, Sm CA* (12), and Sm CA* (13) phases decrease with decreasing cell thickness, and the Sm CA* (13) phase is more stable than the Sm CA* (12) phase. The relative stability of any phase is found to be due to its large polar anchoring strength and low free energy compared to other phases in a cell. Experimental results are found to agree with the theory.
