  • Integration of the developed grid into a display-type retarding field analyzer.
  • Measurement of Au 4f photoemission spectrum to estimate energy resolution.
  • Observation of photoelectron holograms in MoS2.

Main Results:

  • The developed spherical grid offers a wide acceptance angle of ±52°.
  • An energy resolution (E/ΔE) of 2000 was achieved with the modified RFA.
  • Clear photoelectron holograms were observed, demonstrating the RFA's capability for advanced imaging.

Conclusions:

  • The novel micro-holed spherical grid significantly enhances RFA energy resolution and acceptance angle.
  • The developed RFA is effective for advanced spectroscopic techniques, including photoelectron holography.
  • This innovation paves the way for more sensitive and detailed surface analysis.
