Quantitative estimation for the limiting mobility (5x10-4 m2/Vs at room temperature) is obtained in the framework of Landau-Khalatnikov equation of motion and generalized Ginzburg-Landau-Devonshire model, using model parameters estimated from results of independent experiments Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2008
