Abstract
The influence of electron injection from the metal electrode into organic liquid crystalline film, comprised of the polar molecules, such as 4-n-pentyl-4′-cyanobiphenyl, on the orientational ordering, metal work function, and self-diffusion processes was investigated. The metal work function and the set of order parameters were investigated experimentally, using the optical techniques, whereas the orientational self-diffusion process was investigated theoretically, in the framework of the molecular model which takes into account, on the one hand, the random walk theory for calculation of the rotational self-diffusion coefficient, and, on the other hand, the effect of the injected carrier for calculation of the orientational distribution function.
