Transport at Nanoscale Interfaces Laboratory

Our interdisciplinary team gathers physicists, materials scientists, (bio-) chemists, and engineers focusing on bringing novel materials to devices. We are interested in understanding the fundamental electronic, optoelectronic, thermal and ionic transport processes involved in atomically-precise nanostructures and low-dimensional materials. The heterogeneous integration of novel nanomaterials requires custom-made methods for nanoscale patterning and interfaces nanostructuring. Overall, we strive to master the chain of competences leading from designer materials with tailored quantum properties to devices with targeted application in information & quantum technology, energy conversion & storage as well as biochemical sensing & diagnostics.
