Functional Oxides and Molecules

Our recent research topics are focussed on:

Functional oxide filmsThin film oxide dielectric, ferroelectric and superconducting systems are deposited via magnetron sputter technology, PLD and MOCVD (cooperations). The focus of this work lies on the optimization of the deposition process for various applications ranging from energy applications to information and (bio-)sensor technologies.
Multiferroics and ferroelectric devicesThe ferroelectric properties (ranging from ferroelectric-to-dielectric transition temperature, permittivity, piezoelecticity to applications like surface accoustic wave sensors and actuators) of various oxides (e.g. (Ba,Sr)TiO3 or (K,Na)NbO3) are engineered via strain caused by the lattice mismatch between substrate and film.
Vortex matter and fluxonic devicesIn the framework of the European projects quantized flux (vortices) are manipulated in nanostructured HTS-films at dc to microwave frequencies leading to novel fluxonic concepts. Furthermore, the critical properties of coated conductors are analyzed in a special cryoelectronic setup for high current (up to 600A) experiments.
Molecular electronics and interfacesPreparation, characterization and optimization of (self-assembling) molecular layers, mixed molecular layers and molecular multilayers for information and (bio-)sensor technologies. Developement of novel sensor strategies based on planar capacitive detectors, FETs and SAWs.
