Welcome to the web page of the NANO-PHYSICS group of the laboratory for solid state physics at ETH Zürich. Our research focuses on the preparation of ultra-small semiconductor structures with the aim to investigate experimentally new, unusual and unexpected physical systems. In particular we are interested in structures that operate at the crossover between classical physics and quantum physics where several exciting and still unresolved puzzles await their discovery. More detailed information about our research can be found in the list of references as well as in the research subsection.
