Analysis of thermally dielectric relaxation phenomena in organic monolayer films by Debye Brownian motion equation

The thermally dielectric relaxation phenomena in organic monolayer films on a material surface have been analyzed on the basis of the rotational Debye Brownian motion equation. The orientational disordering of monolayers polarized with biasing is discussed with respect to two phases, i.e., the liquid phase and the liquid-crystalline phase, with consideration of the dielectric relaxation time τ and the friction constant ξ of monolayers. The interface effect and the intermolecular interaction are taken into consideration in the analysis.
