Abstract:
Optical reflectivity studies have been conducted upon thin free-standing films of an antiferroelectric liquid crystal possessing the bulk phase sequence Sm C(*)(A)-Sm C(*)(alpha)-Sm A. Electrically induced field independent and field dependent structural transformations were observed above the bulk Sm C(*)(A)-Sm C(*)(alpha) transition temperature. The anisotropy of the reflectivity was measured for different states in thin films. Our data provide direct evidence of structures without the short-pitched helix in the temperature region between the antiferroelectric Sm C(*)(A) and untilted Sm A structures.

Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
