Cy. Chao et al., PHASE-BEHAVIOR OF LIQUID-CRYSTAL FILMS EXHIBITING THE SURFACE SMECTIC-L PHASE, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(6), 1998, pp. 6757-6760
Free-standing smectic films of a liquid crystal exhibiting the hexatic
smectic-Lphase have been studied using electron diffraction and optic
al textures. The films show a rich phase diagram as a function of thic
kness and temperature. A possible phase transition within the surface
smectic-Lphase is observed.
