The L. J. Wong Group on X-ray & Free Electron Quantum Nanophotonics is a leading research group in X-ray photonics, having been recognized as a 2024 Falling Walls Winner in Physical Sciences for “Breaking the Wall of Quantum X-ray Tech” by the Falling Walls Foundation. [Group website: https://sites.google.com/view/ljwgroup]. We leverage advances in nanomaterials and quantum physics to realize breakthroughs in X-ray/EUV technologies for applications including EUV lithography and X-ray inspection.
We have three openings for Computational, Theoretical and/or Experimental talent – see below.
1. Research Fellow, Computational EUV Nanophotonics
We are seeking a Research Fellow to spearhead cutting-edge research in the computational and theoretical modeling of free-electron-driven EUV nanophotonics. Working closely with experimentalists, the research fellow will lead the study of generating and manipulating EUV radiation on the nanoscale, towards the vision of a chip-scale, high-power EUV source for applications including EUV lithography and imaging.
Key responsibilities include:
-
Developing theoretical and numerical frameworks in free-electron-driven EUV nanophotonics, and performing simulations to mold the flow of EUV light using nanomaterials and nanostructures.
-
Programming of software tools
Required qualifications and competencies include:
-
Proficiency with electrodynamics and electromagnetism; familiarity with quantum physics/quantum electrodynamics is a plus.
-
Proficiency in scientific programming e.g., C, C++, Python etc.
2. Research Fellow, Computational X-ray Nanophotonics for Phase Contrast Imaging
We are seeking a Research Fellow to spearhead cutting-edge research in the computational and theoretical modeling of free-electron-driven X-ray photonics. Working closely with experimentalists, the research fellow will lead the study of coherent X-ray emission from free-electron-driven van der Waals materials, and the use of this platform for realizing X-ray phase-contrast imaging on a table-top scale.
Key responsibilities include:
-
Developing theoretical and numerical frameworks in free-electron-driven X-ray nanophotonics– i.e., modeling the physics of free electrons impinging on nanomaterials like van der Waals crystals, and subsequent coherent X-ray emission and imaging processes.
-
Programming of software tools
Required qualifications and competencies include:
-
Proficiency with electrodynamics and electromagnetism; familiarity with quantum physics/quantum electrodynamics is a plus.
-
Proficiency in scientific programming e.g., C, C++, Python etc.
3. Research Fellow, Experimental X-ray Nanophotonics for Phase Contrast Imaging
We are seeking a Research Fellow to spearhead cutting-edge research in the experimental study of free-electron-driven X-ray photonics, with the goal of using such a source to achieve X-ray phase-contrast imaging on a table-top scale.
Key responsibilities include:
-
Spearheading experiments on free-electron-driven X-ray nanophotonics and phase-contrast imaging in customized scanning electron microscope (SEM) and transmission electron microscope (TEM) setups
-
Characterization of material samples and equipment related to experimental objectives
Required qualifications and competencies include:
-
Familiarity with the use of vacuum electronics and/or free-electron-based equipment, including but not limited to SEMs and TEMs
-
Background in free-electron-driven nanophotonics and X-ray generation is a major bonus
