✦ Synopsis
The flow of water through a system filled with anthracene crystals was examined. For other materials it is known that the flow causes a difference in the potential and the short-circuit current. We found that this potential, which is the electrokinetic potential, can be described using a strictly determined space charge distribution of charge carriers near the anthracene crystals and a given model of the water flow between the crystals. The aim of this paper is to present the influence of the spatial charge carrier distribution near the crystal surface on the potential and the current. Considering the laminar flow of water, we can estimate the electrokinetic potential and the current which occur because of the movement of carriers. This movement is forced by the water flow. Achieved values of the potential and the current were about 1 V and 1 pA respectively. Theoretical calculations agree with our experimental results
