Research Associate - MeV UED

Job ID 1604 Date posted 01/22/2019


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 Division 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 complemented 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.

MeV ultrafast electron diffraction (UED) technique provides unique characterizations of the structural dynamics induced by photoexcitations in a wide range of correlated materials and quantum materials. The UED results have been demonstrated to be key to probe the interactions of intertwined charge-spin-orbital-lattice degrees of freedom for the understanding of the materials' functionalities. Currently, the MeV UED experiments confront challenges from sample preparations and technical limitations, which are critical for the scientific explorations using UED. The successful candidate will address the issues in the UED sample-preparation, contribute in upgrading the instrument and explore specific science using modified UED. The project is sponsored by the Department of Energy Early Career Award. The successful candidate will work with Dr. Jing Tao for a one-year appointment with potential renewal for an additional year.



The successful candidate will use and/or develop cutting-edge methods/protocols to prepare MeV UED samples from 3D bulk single-crystalline materials. Moreover, the successful candidate will be heavily involved in the MeV UED instrument upgrade by modifying its mechanical/electrical components with integrated laser system so that the advanced UED results can be delivered with more tunable experimental parameters. The successful candidate will summarize technical developments and scientific findings in publications and talks.



  • PhD in condensed matter physics, chemistry, materials science or related field.
  • Experience in instrumentation (to design and install mechanical/electrical components for instrument upgrade).
  • 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 TEM imaging techniques.
  • 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:

- Experience in nano-fabrication and lithography (clean room level), chemical deposition and plasma etching.
- Experience in sample synthesis methods such as thin-film deposition.
- Experience in pump-probe techniques.
- Experience in in situ TEM studey.
- Experience in optics and laser systems.
