N2 - The electrical potential distribution in a model capacitor specimen, made of single-crystalline BaTiO 3 and thin Pt plates, has been revealed by electron holography. In order to represent the inherent potential distribution related to the capacitance, undesired phase information was eliminated by the analysis of electron holograms acquired in various conditions of applied voltage; the undesired information includes signals due to electrical charging, thickness variation, and modulation of the reference electron wave by a long-range electric field. The observation of electric potential showed reasonable agreement with simulation for the model specimen.
