Materials Science
investigation of material properties
Material Science is the design and discovery of new materials, particularly of solids. These new materials require analysis on the nanometer scale to fully understand the intrinsic properties of the surface and bulk. For this analysis, different measurement schemes are offered, such as low temperature confocal microscopes (CFM) for RAMAN measurements, setups for conductive tip AFM and Kelvin probe force microscopy (KPFM) as well as the double rotator 3DR or the Tramea TMS measurement setup. The environments are generated using closed cycle liquid helium free cryostats with temperatures between 300K and 2K. High fields up to 12T are possible and expand the options for measurements.
