Postdoctoral Research Associate - Optoelectronic Properties of 2D Heterostructures

Date: Mar 17, 2023

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 9547 


Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.


We are seeking a Postdoctoral Research Associate who will support the Functional Hybrid Nanomaterials group, Nanomaterials Synthesis Section, at the Center for Nanophase Materials Sciences (CNMS), Physical Sciences Directorate (PSD), Oak Ridge National Laboratory (ORNL). You will perform research exploring fundamental optical and electronic properties of electronically or optically excited nanomaterials, especially 2D materials and heterostructures for applications in quantum information science, sensors, or energy-related technologies.  


You will work with a team of researchers to assemble and integrate novel 2D materials into device architectures and lead the combined measurement of their electrical and optical properties, such as single photon emission, bias-controlled interlayer excitons, electroluminescence, etc. You will utilize existing characterization setups and work to develop and integrate new optical systems on current platforms, including novel cathodoluminescence SEM, photoluminescence/Raman/SHG/absorption microscopy, and ultrafast pump-probe microscopy.  You will also work across groups at the CNMS to integrate optical spectroscopy methods into existing scanning probe and electron microscopes to enable new capabilities.


Major Duties/Responsibilities: 

  • Enhance existing optical spectroscopy and electronics setups and expertise (e.g., cathodoluminescence SEM, photoluminescence/Raman/SHG/absorption microscopy, and ultrafast pump-probe microscopy platforms) and integrate optical systems into new characterization platforms (e.g., scanning tunneling microscopes, scanning probe microscopes, scanning transmission electron microscopes)
  • Work on the assembly and integration of novel 2D materials into device architectures designed to allow combined measurement of their electrical and optical properties.
  • Report and publish scientific results in peer-reviewed journals in a timely manner.

Basic Qualifications:

  • Ph.D. in physics, optics, materials science, or a closely related field within the last five years.
  • Previous research experience in experimental quantum optics, ultrafast optics, or nanophotonics.
  • Experience in spectroscopy of 2D materials


Preferred Qualifications:

  • Experience in optics, lasers, and building optical spectroscopy platforms
  • Experience in 2D material heterostructure assembly.
  • Experience in laser-material interactions.
  • Experience in ultrafast pump probe spectroscopy
  • Experience in cathodoluminescence and photoluminescence microscopy
  • Experience in solid-state single photon sources and spin qubit measurement techniques
  • Experience in device fabrication and characterization
  • Characterization of materials with transmission electron microscopy and spectroscopy, preferably STEM imaging and EELS methods.
  • Characterization of materials with scanning probe microscopy and scanning tunneling microscopy.
  • Familiarity with 2D materials synthesis by CVD or PLD
  • Background in data acquisition, instrument automation, and data processing using Python.


We are seeking a person with the ability to work well in a dynamic research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever-changing research/programmatic needs. The candidate should have excellent written and oral communication skills and the ability to communicate in English to an international scientific audience. An excellent record of productive and creative research shown by publications in peer-reviewed journals will be positively considered.


Please submit three letters of reference when applying to this position. You can upload these directly to your application or have them sent to with the position title and number referenced in the subject line.
