Synchrotron X-Ray Observation of Surface Smectic-I Hexatic Layers on Smectic-C Liquid-Crystal Films
(American Physical Society, 1987)
Synchrotron x-ray diffraction methods employing a position-sensitive detector were used to study smectic-C (SmC) and smectic-I (SmI) phases in thin (2–6 molecular layers) liquid-crystal films of 4-(n-heptyloxy)benzyliden ...
X-Ray and Optical Studies of the Thickness Dependence of the Phase Diagram of Liquid-Crystal Films
(American Physical Society, 1987)
A comprehensive study of the thickness dependence of the phase diagram of freely suspended films of the liquid crystal 4-n-heptyloxybenzylidene-4-n-heptylaniline (7O.7) between \(50 and 69^{\circ}C\) is reported. In thick ...
