Nanocomposites composed of a self prepared Ferroelectric Liquid Crystalline (FLC) matrix and different nanomaterials
show pronounced reduction of important parameters like spontaneous polarization, switching time but no change of the
tilt angle. As a typical subject silver nanoparticles where characterized. A pronounced increase of resistivity where
described by comparing the pure FLC mixture with properties of FLC nanocomposites. Ion capturing due to silver
particles has been discussed. Photoluminescence originated by the terphenyl compound and enhanced due to the Silver
Surface Plasmon Resonance has been described.
In the framework of the one-dimensional mean-field (MF) drift-diffusion approach the well-defined boundary conditions far away from the metal/insulator contacts of a planar metal/insulator/metal system are used to determine the boundary condition at the interface itself. The novel self-consistent boundary condition linking the carrier density and the electric field at the interface enables a straightforward description of the current voltage (IV) characteristics in forward and reverse bias bridging space charge and injection-limited regimes and accounting for barrier lowering from the potential drop in the used contact materials. Yet, because of the low carrier density in the insulator under injection limitation, single-particle phenomena, such as the Schottky effect, must be considered. We reconsider the validity of the MF approach, depending on the external bias and the prevailing injection barriers. For the crucial parameter window where the MF approach fails and single-particle phenomena become important, a modification of the boundary conditions at the insulator/metal interface is proposed to account for the discrete nature of carriers. The difference between the thus modified MF and the unmodified MF approach is illustrated by several examples.
