ANALYSIS OF THERMALLY DIELECTRIC-RELAXATION PHENOMENA IN ORGANIC MONOLAYER FILMS BY DEBYE BROWNIAN-MOTION EQUATION

The thermally dielectric relaxation phenomena in organic monolayer fil ms on a material surface have been analyzed on the basis of the rotati onal Debye Brownian motion equation. The orientational disordering of monolayers polarized with biasing is discussed with respect to two pha ses, i.e., the liquid phase and the liquid-crystalline phase, with con sideration of the dielectric relaxation time tau and the friction cons tant xi of monolayers. The interface effect and the intermolecular int eraction are taken into consideration in the analysis.
