Physical materials science & Artificial materialsDuring the last decade a tremendous progress has been made in the fabrication of (complex) oxide thin films. To name a few, these are the epitaxial growth technique, understanding of the properties of their defect structure, atomic-level control of their layering, the manipulation of the oxygen contents and dopant densities, etc.

Chemical materials science & Nanostructured materialsBesides physical deposition techniques, a part of the IMS group uses chemical synthesis routes to fabricate novel nanostructured oxide materials. Examples of these are micropatterned oxide films for electronics and sensors, nanotubes for application in nanofluidic devices, nanoporous ceramic membranes, and hybrid organosilane thin films.

Novel devices & ApplicationsMost of the work in the Inorganic Materials Science is devoted towards application in novel devices. Our primary goal is to elucidate the effects of size, structure, and interface of atomically controlled nanostructures made from (sometimes artificially constructed) complex materials, with special attention to properties such as conductivity, spin polarization, ferroelectricity, and optical nonlinearity.

Interface science & Thin film technologyPulsed laser depostion of complex oxides. The possibility of studying the epitaxial growth of oxide materials during deposition at relatively high pressures, so-called high pressure RHEED, has significantly increased our ability to construct artificial layers and junctions.

AnimationsHere you can find various animations, which have been made to clarify the working principle of high pressure RHEED with pulsed laser deposition.
