Using x-ray photoelectron diffraction the authors show the experimental and simulated images for the Ag3d5/2 core level.

While this week’s image reminded me of the kaleidoscopes I had as a kid, the paper by A Crepaldi et al actually explores the electronic and structural properties of a lead monolayer grown on a gold substrate.

The band structure of a 2D layer is known to be influenced by the underlaying substrate material. Known interactions include the nature of the chemical bonds and surface reconstruction, but in this work the authors explore the orbital dependence of the adlayer and substrate materials.

You can read their results, including the additional subtle influences they discovered here.
