Isotropic-nematic transition in liquid crystals confined between rough walls
arXiv:cond-mat/0511198 · doi:10.1016/j.cplett.2005.11.010
Abstract
The effect of rough walls on the phase behaviour of a confined liquid crystal (LC) fluid is studied using constant pressure Monte Carlo simulations. The LC is modelled as a fluid of soft ellipsoidal molecules and the rough walls are represented as a hard wall with a number of molecules randomly embedded in them. It is found that the isotropic-nematic (IN) transition is shifted to higher pressures for rougher walls.
