| contents | Influence of the adsorption energy on the dielectric contribution to the anchoring energy of nematic liquid crystals H.A. Pereira L.R. Evangelista D. Olivero G. Barbero Física, Astronomía y Matemáticas The influence of the ionic adsorption on the anchoring energy of a nematic liquid crystal sample is investigated. We determine the behavior of the anchoring energy as a function of the thickness of the sample, and as a function of the adsorption energy of ions. We show that the contribution to the anchoring energy, due to ionic adsorption, can be of the same order of magnitude of the bare anchoring strength. Our analysis generalizes similar calculations previously published by incorporating the effect of adsorbed charges on the potential and field profiles in the sample. 2002 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413505020 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.32 |
