GIMMIK - Production of graphene on an industrial scale
Graphene consists of only one layer of carbon atoms and has been considered a "wonder material" since its discovery. The extreme strength and flexibility of the material is of particular interest. It also has a higher electrical conductivity than metals and is transparent. The unique properties of the thinnest material in the world could enable a wide range of applications, but there are very few products on the market to date. Some improvements, e.g. in sensors, have led to a significant increase in sensitivity. Transistors, the heart of communications technology or computer systems, could also be realized with particularly high clock frequencies. So far, however, these have only been laboratory demonstrations and not processes suitable for production. The most urgent problem is the poorly defined and reproducible quality of the graphene layers. However, a high and reliably reproducible quality of the electrically functional materials is indispensable for implementation on an industrial scale.
Gas phase deposition is a scalable process for the production of large-area graphene layers. In the GIMMIK project, the production of graphene layers is to be evaluated for the first time under industrial conditions. The weak points in the corresponding processing are identified and ways to eliminate the sources of error are developed. In addition, the transfer of the properties of graphene to electrical components is to be tested by integration into a material environment. This aspect shall be investigated with focus on the evaluation of graphene quality, but also with regard to the improvement of component properties. In parallel, methods for the large-area, contact-free characterization of graphene are being developed, which do not yet exist. The aim of the project is to develop methods to ensure a consistently high graphene quality as a basis for production suitability for deposition and integration processes.
The aim of the GIMMIK research project is to expand graphene technology for electronic components and bring it up to production standards. If successful, an international breakthrough will be achieved in the industrial application of graphene, which will strengthen the participating companies and Germany internationally as a science and business location due to its high potential for exploitation.
