Position Overview

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.

Essential Duties and 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

Minimum Qualifications

• 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

Desired Qualifications

• 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

Working Environment

• The postdoctoral researcher will work in a collaborative, research-intensive environment based primarily at Brookhaven National Laboratory, with close coordination with the Arizona State University research group. The position involves access to advanced experimental facilities and instrumentation for photocathode fabrication, activation, and characterization, as well as computational resources for charge transport and multiscale simulations. The researcher will interact regularly with multidisciplinary teams focused on electron source development, spin-polarized electron emission, and nanophotonic device physics, and will be expected to contribute to an active, safety-compliant national laboratory research setting.
