The fabrication of defined nanostructures, i.e. objects ranging between 0.1-100~nm, is an indispensable prerequisite for the discovery and exploration of new exciting phenomena in modern solid state physics. Impressive examples are the quantum Hall effect, the spin Hall effects, Luttinger liquid behavior, Majorana fermions, etc.
The institute of Solid State physics as a long tradition and ample experience in the fabrication of nanostructures with atomic precision using both top-down and bottom-up techniques. State of the art cleaning room facilities in combination of deposition techniques under ultra-high vacuum conditions allow broadband fabrication of functionalized nanostructures with tailored properties. Among others, GaAs-heterostructures and quantum dots, graphene nanostructures as well as thin insulating films and contacts for single molecules belong to the portfolio of the institute.
