Quantum Materials & Devices
The possibility to design materials at the atomic and molecular level has enabled the observation, control and device implementation of novel quantum phenomena. We search for novel quantum materials and explore their fabrication on demand by combining one- and two-dimensional structures and/or the tailoring of interfacial properties. We address the electronic and optoelectronic properties by spectroscopic and electrical transport measurements and novel imaging techniques. Of particular interest is the manipulation of spin phenomena without the use of magnetic fields and the interplay and coexistence of topologically trivial as well as non-trivial states.
