The first 5G mobile radio antennas are currently being installed in Germany - UDE is already researching high-frequency technologies for the day after tomorrow: 6G terahertz communication with more than 100 Gigabit/s data rates, state-of-the-art radars and other applications suitable for everyday use. In order to be able to invest in new production facilities and equipment, the university will receive over 6.5 million euros from state and EU funds*. This will create a Terahertz Integration Centre (THzIZ) that is unique in Germany.

Terahertz technology can do much more than transmit hundreds of gigabits per second: "It makes it possible to determine the position of objects with high precision and at the same time analyze their chemical composition. The fast waves have huge potential," says Prof. Dr. Nils Weimann. "In medical technology, terahertz radiation, which is harmless to humans, could help in the investigation of skin cancer, for example. Other medical applications for mobile THz sensors are the analysis of breathing air for diagnosis or the imaging of the sole of the foot for the evaluation of diabetes.

However, it is not yet possible to produce new systems on an industrial scale at low cost. This could change. "With the new terahertz integration center, we can now selectively expand our successful research and develop innovative terahertz modules for mobile and everyday applications to market maturity," says Weimann.

nnovative electronic and optoelectronic THz semiconductor chips are already being designed at the UDE, among others within the framework of the MARIE Collaborative Research Center. The "ForLab smartBeam" laboratory was recently set up at the Center for Semiconductor Technology and Optoelectronics (ZHO): The research there is intended to enable precise and reliable environment recognition for robots and autonomous vehicles. The new million-dollar grant will provide the ZHO with additional state-of-the-art production facilities and measuring equipment.

*The €6.5 million grant comes from the NRW Research Infrastructures programme and the European Regional Development Fund (ERDF). The THzIZ is set up and coordinated by Professors Dr. Nils Weimann, Dr. Andreas Stöhr, Dr. Daniel Erni and Dr. Thomas Kaiser.
