1A06 永久双極子を持つ液晶分子の電界に対する配向挙動への壁面の影響 II : ダイポール-ダイポール相互作用とSmCの形成

抄録

Changes of molecular alignment due to the electric field are studied by constant temperature molecular dynamics simulation of the Gay-Berne system sandwiched by walls, where every particle has a permanent dipole along the molecular long axis. The homeotropically anchored smectic phase (SmA2) driven by electric field at homogeneous anchoring wall is observed under the condition where the homogeneous anchored one (SmA1) is stable without the field, while SmA1 is induced at homeotropic anchoring wall by the transverse electric field. The order of smectic A is destabilised by the dipole-dipole interaction and eventually a sort of order of smectic C phase appears in the strong electric field region.
