The activity 'Functional Oxide Films and Sensors' is focused on the development of complex oxides thin film systems (single to multilayers as well as micro- and nanostructures), the analysis, understanding and engineering of their physical and electronic properties, and their application in the field of microwave and sensor devices for bio and chemical applications. Special emphasis is dedicated to the physics of nanoscale dielectric, ferroelectric and superconducting oxide systems, respectively.

 

The following major topics are included:

  • complex oxides films and film systems - from analysis and simulation of the deposition process towards complex micro and nanostructures
  • electronic properties of oxide films, multilayers and nanostructures - ranging from di-, para- and ferroelectricity to superconductivity
  • engineering of the physical properties of oxide films- methods ranging from chemical substitution to strained layers
  • vortex matter in micro- and nanostructured superconducting films - towards novel fluxon devices
  • oxide thin film sensor devices for bio and chemical applications

The research activities are embedded in the activities of the 'Centers of Nanoelectronic Systems for Information Technology' (CNI). They are part of national and international projects, networks and cooperations with industry.
