Research Associate - Ultrafast Electron Diffraction

Job ID 1528 Date posted 11/13/2018

Brookhaven National Laboratory is a multipurpose research institution funded primarily by the U.S. Department of Energy’s Office of Science. Located on the center of Long Island, New York, Brookhaven Lab brings world-class facilities and expertise to the most exciting and important questions in basic and applied science—from the birth of our universe to the sustainable energy technology of tomorrow. We operate cutting-edge large-scale facilities for studies in physics, chemistry, biology, medicine, applied science, and a wide range of advanced technologies. The Laboratory's almost 3,000 scientists, engineers, and support staff are joined each year by more than 4,000 visiting researchers from around the world. Our award-winning history, including seven Nobel Prizes, stretches back to 1947, and we continue to unravel mysteries from the nanoscale to the cosmic scale, and everything in between. Brookhaven is operated and managed by Brookhaven Science Associates, which was founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, and Battelle, a nonprofit applied science and technology organization.

The Condensed Matter Physics and Materials Science Department has a very strong tradition of research into strongly correlated materials using several experimental techniques including x-ray scattering, neutron scattering, electron microscopy and photoelectron spectroscopy, etc.  This is complimented by excellent sample synthesis capabilities and strong theoretical support.  The X-ray Scattering group specializes in Resonant Inelastic X-ray Scattering (RIXS), Bragg Coherent Diffraction Imaging (BCDI), and X-ray Total Scattering for Pair Distribution Function (PDF) and benefits from close collaboration with beam-lines at the National Synchrotron Light Source II.

Brookhaven National Laboratory was recently awarded a grant entitled, Dynamics and Control of Magnetic and Charge Order in Complex Oxides -- one of 10 nationwide programs for advancing x-ray free electron laser studies aiming to advance our understanding of chemical and materials science.  The collaboration involves 8 PIs and 5 research associates working together to deliver detailed pictures of ultra-fast spin and charge behavior in complex oxide materials and how this organizes into domains once it couples to the lattice.  This multi-degree of freedom, multi-length-scale understanding of canonical strongly correlated oxides is a vital step towards "properties on demand" via strategic ultra-fast excitation of quantum materials.  As a part of the collaborative effort, ultrafast electron diffraction (UED) technique will provide detailed structural characterization that complements the information obtained by time-resolved (tr) BCDI and RIXS.

The successful candidate will work with Jing Tao and Yimei Zhu in the Electron Microscopy and Nanostructure / Ultrafast Electron Diffraction Group.

The successful candidate will deliver the information of structural dynamics that is correlated to the magnetic and charge degrees of freedom in desired complex oxides (cuprates and iridates).  This requires cutting-edge techniques for preparing MeV UED single-crystal samples, which can be used in trBCDI and trRIXS as well.  The successful candidate will be involved in performing UED experiments, comparing the outcome with those from trBCDI and trRIXS, and summarizing the scientific findings in publications and talks.

  • PhD in condensed matter physics, chemistry, materials science or related field

  • Experience in TEM characterizations, including imaging techniques and electron diffraction

  • Effective written and oral communication skills

  • Self-motivated and able to work both independently and as part of a team

Preferred Knowledge, Skills and Abilities:

  • Capability in data analysis and interpretation in electron scattering techniques

  • Sample-preparation skills and methods for the MeV UED single-crystal specimens, including mechanical polishing, focused ion beam milling, noble-gas ion sputtering.

  • Experience in instrumentation, nano-fabrication and lithography (clean room level), chemical deposition and plasma etching.

  • Experience in pump-probe techniques

  • Experience in in situ / operando TEM study   

    BNL policy requires that appointments be made to individuals who have received their PhD within the past five years.

    At Brookhaven National Laboratory we believe that a comprehensive employee benefits program is an important and meaningful part of the compensation employees receive.  Our benefits program includes but is not limited to:

    - Medical Plans
    - Vacation
    - Holidays
    - Dental Plans
