Postdoctoral Research Scholar

Arizona State University • NY-Remote, NY

4d • $72,000 - $72,000 • Onsite

About The Position

The Postdoctoral Research Scholar will be stationed at Brookhaven National Laboratory as required by the grant and will conduct experimental and computational research on nitride-based III-V photocathode heterostructures. The role supports advanced development and characterization of next-generation polarized electron sources through integrated experimental and simulation-based approaches.

Requirements

• Ph.D. in Physics or closely related field (or Ph.D. completion expected within the current academic timeline)
• Research experience in photocathode science, electron beam physics, or related accelerator physics
• Demonstrated ability to conduct independent, research-intensive work in experimental physics

Nice To Haves

• Experience with nanostructured III-V photocathodes and/or negative electron affinity (NEA) materials
• Prior work with high-voltage electron guns and beamline diagnostics
• Experience in ultra-high-vacuum (UHV) systems and photocathode activation techniques (e.g., Cs/NF₃)
• Strong background in electron optics design and beam transport simulations
• Proficiency in nanophotonic modeling and charge transport simulations (e.g., FDTD, CHARGE or similar tools)
• Experience with QE measurements, spin-polarization systems, and optical system design
• Strong computational skills (e.g., Python, MATLAB) for data analysis and modeling

Responsibilities

• Develop and optimize electron optics systems for spin-polarization measurements of photocathodes
• Perform Cs/NF₃ activation of III-V photocathode surfaces under ultra-high-vacuum conditions
• Conduct quantum efficiency (QE) spectral response measurements and related beam diagnostics
• Design and implement optical setups for spin rotation and polarization measurements
• Perform charge transport modeling and simulations of III-V semiconductor photocathodes
• Support experimental operations at Brookhaven National Laboratory and ensure proper system integration
• Analyze and interpret experimental and simulation data to guide photocathode performance optimization
