Our research is focused on the development, fabrication and characterization of nano- and optoelectronic devices based on the group-IV semiconductors Silicon, Germanium and Tin. We also explore the use of functional oxides. We combine materials research with the development of novel device concepts with applications ranging from sensors to spintronics. One example is the use of low-dimensional semiconductor heterostructures and metallic nanostructures to develop integrated biosensors. We are one of 12 ForLabs in Germany that have recently been equipped with state-of-the-art processing and characterization equipment to that purpose.



Our paper "Strong optical coupling of lattice resonances in a top-down fabricated hybrid metal-dielectric Al/Si/Ge metasurface" has been accepted for publication in Nano Letters.
