TL;DR: In this paper, the authors describe the development and characteristics of a new aluminum solid electrolytic capacitor in which organic semiconductors are substituted for manganese dioxide, and a basic approach to obtaining a uniform and adherent film suitable for an etched aluminum foil is given, along with limitations on the use of the organic semiconductor.
Abstract: This paper describes the development and characteristics of a new aluminum solid electrolytic capacitor in which organic semiconductors are substituted for manganese dioxide. The highly conductive ion-radical salts based on 7, 7, 8, 8-tetracyanoquinodimethan were chosen because of their prominent effect on capacitor self-healing. The solid electrolyte layer of a thin uniform coating was deposited from a solution of the semiconductor and polymers. A basic approach to obtaining a uniform and adherent film suitable for an etched aluminum foil is given, along with limitations on the use of the organic semiconductor. Emphasis is placed on the effect of the polymers on the growth and adsorption of the organic-semiconductor crystals during electro formation. Much improvement was realized in capacitor performance, viz. the Iow leakage current, the extended ratio of breakdown-to-formation voltage, and stable frequency characteristics. It may be concluded from the laboratory experiments that production of high-performance organic semiconductor solid capacitors will probably be feasible in the near future

TL;DR: In this article, the ground-state wave-function of a few organic semiconductors (namely TCNQ salts and the PDC charge transfer complex) is computed ab initio.
Abstract: We report an attempt of ab initio computation for the ground-state wave-function of a few organic semiconductors (namely TCNQ salts and the PDC charge transfer complex) for which we show that electrical conduction appears to look strongly like that of a band-gap semiconductor.

TL;DR: An electrophotographic photo-sensitive plate which comprises an electrically conductive base, an inorganic photoconductive thin layer of selenium or seenium-arsenic formed on the conductive bases, and an organic semiconductor layer, for example, of polyvinyl carbazole further deposited on the inorganic photonductive layer is shown in this paper.
Abstract: An electrophotographic photosensitive plate which comprises an electrically conductive base, an inorganic photoconductive thin layer of selenium or selenium-arsenic formed on the conductive base, and an organic semiconductor layer, for example, of polyvinylcarbazole further deposited on the inorganic photoconductive layer. By the addition of a proper amount of nitrated benzoic acid derivatives to the upper organic semiconductor layer, the increase of residual potential and difficulty of maintaining surface potential in repeated use of the photosensitive plate are remarkably reduced.
