Günter Möbus joined the Department in Oct 2002. He graduated at Stuttgart University in Germany before moving for his PhD and postdoctoral years to the Max-Planck-Institut for metals research in Stuttgart. In 1998 he was awarded an EPSRC Advanced Fellowship, held first at Oxford University, and then at Sheffield University until 2003.

Research interest:

Advanced Characterization and Patterning of Materials on the Nanoscale (Nanometrology & Nanomanipulation).
Development of Electron Microscope based Techniques for Atomic Scale Imaging and Analysis.

Particular research topics

Tomography on the nanoscale for 3D reconstruction of nanoparticles, nanophases and for 3D chemical mapping of composites.
Development of novel instrumentation and data processing procedures for electron microscopy and tomography, including electron energy loss spectroscopy, high-resolution TEM, STEM, and EDX.
Atomistic structure of nanoparticles, surfaces, and interfaces and their determination by quantitative high- resolution electron microscopy. Dynamic structure development and single atom mobility.
Study of atomic scale structure and chemistry of glasses and ceramics, including tracing of element distributions, localised determination of coordination and oxidation states of cations. Microstructure of glass/ceramic nanocomposites and nanoporous materials. Immobilisation of radionuclides in glasses and ceramics.
Electron and ion beam interactions with materials, including irradiation damage studies and patterning of surfaces for nanotechnology applications.
