TL;DR: In this paper, an electrochemical method was used with a single crystal ZnO electrode and with the material of interest dissolved in the electrolyte to measure thermal control coatings, either alone or in formulation of a binder.

TL;DR: In this article, a theoretical approach to the electrothermal properties of such targets is presented, and the preparation and experimental results of the Vidicon targets are reported. But the results are limited to the case of a single image pickup tube operating at room temperature.
Abstract: Some organic semiconducting polymers have a resistivity that varies to a great extent with temperature. Thin membranes made from these suitably doped materials are covered with a coating that absorbs infrared radiation, thus constituting targets for image pickup tubes of the Vidicon type operating at room temperature. After a theoretical approach to the electrothermal properties of such targets, the preparation and experimental results are reported.

TL;DR: In this article, different thermal activation energies of dark conduction in the ohmic and square-law regions have been measured for anthracene, and they have been interpreted in terms of localised dominant exponentially distributed hole and dominant electron levels within the band-gap.

TL;DR: In this paper, experimental data relating to the temperature dependence of the electrical conductivity of aromatic organic compounds are discussed within the framework of the zone (band) model, and the Mott formula is satisfied for anthracene, phenanthrene, and naphthalene, while the dependence of σs/σl on the change in thermal activation energy established by Gubanov for inorganic semiconductors also applies to those organic compounds for which δe is equal to or less than 2 eV.
Abstract: Experimental data relating to the temperature dependence of the electrical conductivity of aromatic organic compounds are discussed within the framework of the zone (band) model. The electrical conductivity of these compounds is determined by the bond energy of the molecular compounds and diminishes with increasing melting point. The Mott formula is satisfied for anthracene, phenanthrene, and naphthalene, while the dependence of σs/σl on the change in thermal activation energy established by Gubanov for inorganic semiconductors also applies to those organic semiconductors for which δe is equal to or less than 2 eV. An analysis of the experimental data indicates than zone (band) theory may be used for organic semiconductors in the melting region if the character of the conductivity is similar in the solid and liquid states and the change in thermal activation energy is small.
