Abstract: The invention refers to GaN Gunn diodes which were produced on a GaN substrate and are suitable for generating millimetre waves with very high po- wer. Due to one particular embodiment and arran- gement of the contacts, it was possible to generate stable current voltage curves with a well marked ne- gative differential resistance using these novel com- ponents. Thereby, significantly higher field strengths than the threshold field strength can be used.


Patent status / Exclusivity: A German patent has already been granted. Nationa- lization procedures have been initiated in Europe and the USA.


Possibility for Cooperation: TransMIT GmbH, on behalf of the Technische Uni- versität Darmstadt (Darmstadt University of Techno- logy, Germany), is looking for • cooperation partners for the further development of the invention,


• distribution partners or • distribution and production partners in Asia, Australia, Canada, Europe and the USA.

Abstract: A method for the production of nanowires has been developed. The wires are arranged between two la- yers to avoid tangling of the wires. The arrangement of the nanowires between two layers is particularly suitable for use in a microreactor or catalyst. Hereby, the fluid is guided through the chamber between the two layers. With the new production method, specific surfaces of up to 5mm2 realized.
