WebbAntiferroelectric liquid crystals (AFLCs) are a type of liquid crystals (SmC*A ) [6-10] in which spontaneous polarization has been created on different layers due to the helical superstructure. The c-director of the adjacent layers of AFLCs is nearly antiparallel to each other because of its anticlinic nature. WebbFERROELECTRIC LIQUID CRYSTALS Ferroelectricity was mainly the subject of solid state material research because of its symmetry requirement. Ferroelectric materials centrowith nonsymmetric space - group must show reversible spontaneous polarization which was not expected in liquids and glassy materials.

WebbHis scientific interests lie mostly in Condensed matter physics, Density functional theory, Electronic structure, Very-long-baseline interferometry and Optics. As part of one scientific family, Changhoon Lee deals mainly with the area of Condensed matter physics, narrowing it down to issues related to the Magnetic structure, and often Multiferroics and Spin-½.
