3、aterials. 3. Short description The position aims at strengthening research efforts at the University of Groningen (RUG) that utilize the new experimental techniques at synchrotron, neutron and free-electron centres for the study of the electronic properties of complex materials. These materials are
4、characterized by competing interactions of spin and orbital moments, polar displacements and structural distortions and lead to phenomena such as unconventional superconductivity, colossal magnetoresistance and multiferroicity. We are looking for candidates interested in utilizing the technical deve

7、y. The synchrotron based centers ESRF, HASYLAB, Advanced Photon Source, Spring 8 have improved their flux, spatial and time resolution enabling novel experimental methods at various beam lines on complex systems. In a few years the next generation light sources such as XFEL at Hamburg will increase
8、the flux further by several orders of magnitude. Likewise the neutron centers expand their possibilities with improved flux and beam properties at ILL, ISIS with a new target station. Also here new centers are being constructed such as the ESS in Lund Sweden. Within The Netherlands the RUG considers
9、 to construct a synchrotron source with properties similar to FLASH of DESY and the University of Delft plans to open neutron beams to external users as a facility.These facilities offer the tools to significantly expand our knowledge about complex materials, in which small perturbations can have a
10、dramatic effect on their properties. Moreover, the theoretical understanding of these techniques such as resonant or coherent diffraction enables a better interpretation of the data. Also the increased spatial resolution offers the possibility to extract information from minute quantities including
11、properties at interfaces and near domain walls. Synchrotron and neutron based research is well established in The Netherlands, including at the RUG. Some techniques have become standard but experimental progress still continues such as including protein crystallography (Prof. Dijkstra at RUG) and te
12、xture analysis e.g. in polymers by SAXS (Prof. ten Brinke, RUG). The group of Prof. Vlieg (RU Nijmegen) studies i.a. surface structures at ESRF. Neutron and X-ray scattering on bulk materials is carried out by the groups of Prof. Brueck (energy materials) and Pappas (spin dynamics, development of ne
13、utron instrumentation) at T.U. Delft. Also noteworthy is the effort of Dr. Goedkoop (UvA) on coherent scattering in magnetic systems. This position intends to make the RUG an important player in the field of synchrotron/neutron research on complex materials. The Netherlands have a strong tradition i
14、n correlated electron materials. The structural and electronic properties of metal oxides are studied in bulk materials by the group of Prof. Golden (UvA) and in thin film samples in the group of Profs. Blank/Rijnders (MESA+, Twente). 5. Research group and institute The position will be embedded in
15、the research group Solid State Materials for Electronics. The aim of the research of the group is to utilize displacive, spin-, charge and orbital degrees of freedom to control the electronic and physical properties of transition metal oxides and molecular compounds. The research integrates the synt
16、hesis of materials in both bulk and thin film form with studies of structural and electronic properties. The results are analysed using modern theoretical methods and concepts using microscopic descriptions and relate to functionality on the nanometer length scale. The objective is to contribute to the fundamental understanding of electronic materials that are technologically relevant for future applications. The group employs a multidisciplina
