Silicon is the basic material that is used in our smart phones, in optical sensors, or in solar cells on our roofs. It is a major outstanding challenge that silicon absorbs incident light only weakly, especially in the red part of the visible spectrum.

In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, opto- and quantum-technology it is crucial to understand how phonons – the vibration of atoms in solids – influence the materials’ properties.
