As part of the THzNanoVision project, scientists at the Department of Electrical Engineering and Information Technology (etit) at TU Darmstadt are researching novel sources for the generation and utilisation of terahertz (THz) waves in order to create the basis for a cross-sectional technology in a wide range of applications in the long term. The core innovation is the patented semiconductor technologies with which biocompatible, inexpensive, powerful and easy-to-install THz sources can be developed.

Such THz sources can be used in a variety of ways in the field of non-destructive material testing, whether for testing tyres, composite materials or quality control of medicines and foodstuffs. Another area of application is large-scale security checks to identify dangerous objects, for example at airports.

In the long term, wireless, high-bit-rate data transmissions over short distances (the so-called last mile) are possible. The aim is to use the technology in places where broadband expansion with fibre optic networks is difficult. In the future, the technology will also form the basis for further applications in the area of 6G data transmission and subsequent generations.

The Darmstadt scientists are also paying particular attention to biocompatibility and health compatibility: compared to conventional alternatives such as X-ray or ultraviolet technologies, terahertz waves are harmless. The sustainably orientated terahertz sources also use gallium nitride material, replacing problematic materials currently used on the market, such as rare indium and toxic arsenide.

The team around the start-up currently consists of the inventor and know-how carrier Dr. Ahid S. Hajo, M.Sc. Deniz Cicek and M.Sc. Yunus Celik. THzNanoVision is also supported by two mentors, Prof. Dr. Sascha Preu and PD Dr.-Ing. habil. Oktay Yilmazoglu. The GaN-based wafers will be provided in collaboration with Prof Armin Dadgar from the University of Magdeburg. In addition, THzNanoVision is supported by a diverse group of advisors who are characterised by their experience and expertise in their respective fields.
