摘要:
A semiconductor device is fabricated and contains a first body made of an organic semiconductor material and a second body made of an electrically conductive contact material, that form a common contact area. First, a body is produced on a substrate, which body may be composed of the contact material or the organic semiconductor material, and an intermediate layer is applied thereon, the intermediate layer containing a reactive dopant. Afterward, a body made of the organic semiconductor material or the contact material is fabricated on the intermediate layer. The dopant contained in the intermediate layer effects a region-selective doping of the organic semiconductor material and, as a consequence, a significant reduction of the contact resistance for the transition of charge carriers between the contact material and the organic semiconductor material.

A method for selectively doping an organic semiconductor 1material in the region of a contact area .1formed between a contact and the organic semiconductor material disposed thereon includes introducing the dopant with the aid of nanoparticles, the nanoparticles being disposed in a manner adjoining the contact area and, as a result, only a very narrow region of the organic semiconductor material being doped. The field increase effected by the nanoparticles results in a further reduction of the contact resistance.

A polythiophene polymer with high charge-carrier mobilities, a method for fabricating the polymer, and a semiconductor component and an organic field effect transistor including the polymer are provided. The polymer has electrical semiconductor characteristics and includes a backbone formed from thiophene groups. The thiophene groups carry a side group in the 3rd and 4th positions that can itself have semiconductor characteristics. The polymers have a high mobility of the charge carriers and are therefore suitable for fabricating electronic components such as field effect transistors.

The invention relates to an OLEEC component and to a production process therefor. This component has an active layer including a novel emitter complex. This complex is formed by the coordination of low molecular weight semiconductors around a central cation. The complexation allows wet-chemical processing of low molecular weight semiconductors. This also allows formation of emitter complexes from effective hole or electron transport materials.

A material is utilized with an electropositive metal. This can be used as post-oxyfuel process for oxyfuel power stations. Here, an energy circuit is realized by the material utilization. An electropositive metal, in particular lithium, serves as energy store and as central reaction product for the conversion of nitrogen and carbon dioxide into ammonia and methanol. The power station thus operates without CO2 emissions.
