Julia Camut from the Institute of Materials Research has successfully defended her dissertation entitled „Development of Mg2(Si, Sn)-based thermoelectric generators: investigating contacting solutions, fabrication process, evaluating measurement reliability and optimization paths via modelling“ at the University of Duisburg-Essen. She has, for the first time demonstrated and characterized magnesium silicide based thermoelectric generators. This is an important step towards the implementation of thermoelectric technology based on sustainable elements.
