In this paper we demonstrate the filling of porous silicon (PS) layers with liquid crystals (LC’s) in order to control the reflectance electrically. The preparation of PS and the choice of the right group of LC’s will be presented. Especially an oxidation of PS is necessary so that the methods and parameters of oxidation will also be discussed. As a first result the increasing and decreasing of the thickness oscillations in the reflectance as a function of the applied voltage can be observed. [less ▲]
