Whether streaming music and movies, watching TV or in the car: The MPEG-H Audio system makes it possible to fully immerse yourself in soundscapes and adjust them to your own preferences. Three researchers from the Fraunhofer Institute for Integrated Circuits IIS representing a large team are being awarded the Joseph von Fraunhofer Prize 2023 for this development.
Researchers first to link silicon atoms on surfaces
First time to produce a silicon polymer
A team consisting of various working groups from the fields of chemistry and physics are now the first to have linked silicon atoms on surfaces. From silicon polymers, the researchers hope for innovative material properties and new, promising candidates for potential applications.
Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials. So-called conjugated polymers are candidates. These organic macromolecules have semi-conductor properties, i.e. they can conduct electricity under certain conditions. One possible way of producing them in the desired two-dimensional – i.e. extremely flat – form is presented by surface chemistry, a field of research established in 2007.
