Title: Meniscus and dislocations in free-standing films of smectic-A liquid crystals
Abstract: A flat, freely suspended film of smectic-A liquid crystal supports a difference, Delta p, across its two free surfaces. The size of meniscus is about 10 mu m, 2 orders of magnitude smaller than the length, and its profile is predicted to be circular, in with our measurement. The measurement of its radius of gives Delta p. We nucleate ex nihilo an elementary edge loop, and from its critical radius and growth dynamics by Delta p), we find the line tension (similar to 8 x 10(-7) and the mobility of an elementary edge dislocation (similar to 4 x 10(-7) cm(2) s/g).
