Using light to investigate materials
The Infrared and Terahertz Science Group uses light to investigate materials for future communication systems and sustainable production, and to investigate the effect of radiation on molecular systems, aiming at a better understanding of radiation-induced damage to materials.
Radiation damage to skin, organs and cellular structures is an important factor for health and life expectancy of humans. In the Infrared and Terahertz Science Group at DTU Electro we are interested in learning more about the first steps of interaction between electrons and bio tissue – with a deeper understanding of the fundamental mechanisms leading to damage, it will become possible to develop better medical treatments.
Another
aspect of our research deals with understanding materials of the future of
computation and communication. We are interested in replacing present-day
materials that may be scarce, highly polluting or expensive with better, faster
and more sustainable materials.
Specialists in terahertz technology
We use short pulses of light of femtosecond duration to shape exactly the optical spectrum needed for our investigations. We specialize in terahertz technology, where we use the peak field strength of such fields for studies of the interaction between light and matter on short time scales and at extreme field strengths.
In this manner, we are able to simulate conditions relevant for semiconductors in next-generation electronics. In particular, we are interested in using the electric field of a light wave for direct control of the flow of electrons.
