Surface Metrology

Department 5.1

Tasks and aims

 

Traceable measuring techniques for dimensional variables of surfaces are the basis for an accompanying quality assurance in research, development and production. In particular for the field of nano-technology there is an additional strong linkage between dimensional and other physical and chemical properties.
The group Surface Metrology regards it as its goal to develop and to improve measurement devices and instruments for the measurement of small structures on surfaces in the fields of micro system technique, nano-technology and the surface measuring techniques (roughness -, hardness - and layer thickness, etc.) in order to reach smaller uncertainties surely. This includes the development and calibration of standards for the dissemination of dimensional properties to DAkkS and industry too.
The group is involved in the Avogadro project as well as in several national and international projects.
