Surface Electronic Structure of Ni-doped Fe3O4(001) with XPS and Fermi Surface Data

Mert Taskin from the University of Zurich provides data supporting a study on the surface electronic structure of nickel-doped magnetite. The dataset includes tab-separated files for angular distribution maps, Fermi surface measurements, and X-ray photoelectron spectroscopy (XPS) data from pristine, as-grown, and post-annealed samples. Analysis was performed using Wavemetrics Igor Pro 7.08 with user-defined macros.

Use Cases

• Analyzing Fermi surface topology based on tab-separated YXZT data files for pristine Fe3O4(001).
• Comparing experimental and simulated angular distribution maps of photoelectrons at different initial-state energies.
• Investigating the effect of nickel doping and annealing on XPS spectra from the Ni 2p core level.

Strengths

• Includes both experimental measurements and theoretical simulations obtained with the RSMS code for direct comparison.
• Provides detailed calibration formulas for electron analyzer data, such as CKE=(MKE-0.58267)/0.99913 for a pass energy of 50 eV.
• Data is structured in consistent tab-separated YXZT or YYYX formats across multiple figures.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
