There are several open PhD positions for students interested in the research fields of solid state and surface physics in the Institute of Experimental Physics IV at the Ruhr Universität Bochum. The successful applicant will investigate the novel size- and shape-dependent physical properties of metal nanostructures. Emphasis will be given to: (i) studying the magnetic properties of nearly 1D and 0D systems, (ii) monitoring size-dependent changes in the electronic properties of nanoscale systems, and (iii) getting insight into the vibrational dynamics of low dimensional systems. State-of-the-art experimental techniques are available in Dr. Roldán’s laboratory for these projects: Atomic and Magnetic Force Microscopy (AFM, MFM), Scanning Tunneling Microscopy (STM), Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), Auger Electron Spectroscopy (AES), Ultraviolet Photoelectron Spectroscopy (UPS), Low Energy Electron Diffraction (LEED), X-ray Diffractometry (XRD), in-situ and ex situ Magneto-Optic Kerr Effect (MOKE), Vibrating Sample Magnetometer (VSM), Superconducting Quantum Interference Device (SQUID), and Molecular Beam Epitaxy (MBE). Furthermore, the selected candidates will also have access to synchrotron based measurement techniques at European and international user facilities, including nuclear resonant inelastic X-ray scattering (NRIXS), X-ray absorption fine structure spectroscopy (XAFS), grazing incidence small angle X-ray scattering (GISAXS), as

well as ambient pressure XPS. Required qualifications include a Master or BS in Physics or Chemistry. Previous experience using any of the techniques mentioned above is not required but would be of benefit. Interested applicants should send their curriculum vitae and the names and contact information for three references by email as PDFs to: [email protected].

There is an open postdoctoral position in the research fields of surface physics and nanocatalysis in the Institute of Experimental Physics IV at the Ruhr Universität Bochum. The successful applicant will utilize UHV-based surface-sensitive techniques to characterize the novel size- and shape-dependent physical-chemical properties of nanostructures. Emphasis will be given to understanding the mechanisms of metal nanoparticle enhanced chemical reactivity by monitoring changes in size, shape, chemical state, and electronic structure of nanoscale systems during heterogeneous and electrochemical catalytic reactions. The reactivity tests will be conducted in UHV and at high pressure (gas/solid nanostructured interfaces), as well in an electrochemical environment (liquid/solid interfaces). The evolution of the structure, chemical state and composition of nanocatalysts at work (in situ and under operando conditions) will be monitored. State-of-the-art experimental techniques are available in Dr. Roldán’s laboratory for these projects: Atomic Force Microscopy (AFM), Scanning Tunneling Microscopy (STM), Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), Auger Electron Spectroscopy (AES), Ultraviolet Photoelectron Spectroscopy (UPS), Temperature-Programmed Desorption (TPD) and Reaction (TPR) with mass spectrometry and gas chromatography, Low Energy Electron Diffraction (LEED), and Molecular Beam Epitaxy (MBE). Furthermore, the selected candidate will also have access to synchrotron based measurement techniques at European and international facilities, including X-ray absorption

fine-structure spectroscopy (XAFS), grazing incidence small angle X-ray scattering (GISAXS), as well as ambient pressure XPS. Required qualifications include a PhD in Physics, Physical Chemistry, Chemical Engineering, or Materials Science. Previous experience using any of the UHV surface analysis equipment mentioned above would be of benefit.
