Abstract
Abstract A capacitor includes two metallic anode bodies positioned close together and having a dielectric oxide coating thereon, a layer of semiconducting material over the oxide coating and a conducting layer over the semiconducting material, the semiconducting layer being between the bodies and the conducting layer at least partially surrounding the bodies to form an integral structure.
