Biomathematics Seminar: Remarkable structures in liquid crystals
4 December 2012 14:00 in CM105
Liquid crystals are ubiquitous in flat panel displays including televisions, lap top displays and mobile phones. However, these organized, self-assembling fluids are far more than simple technological materials as they can exhibit a surprising range of structures, many of which are based on frustration. This talk describes some of the remarkable frustrated structures that can form in liquid crystals that result in properties including ferroelectricity, antiferroelectricity and optical band gaps. The potential for tuning functionality through controlling both the bulk and molecular structures is leading to new soft condensed matter systems that offer routes to a whole family of new applications including electro-optical switches, sensors and all-optical transducers.
