Evaluating covalency using RIXS spectral weights: Silver fluorides vs. cuprates
Ilya Degtev, Daniel Jezierski, Adrián Gómez Pueyo +9
We investigate the electronic structure of AgF2, AgFBF4, AgF and Ag2O using X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS) at the Ag L3 edge. XA…

How orbitals and oxidation states determine apparent topographies in scanning tunneling microscopy: the case of fluorine on silver surfaces
Adrián Gómez Pueyo, Jazmín Aragón Sánchez, Ilya Degtev +11
We use density functional theory calculations to characterize the early stages of fluorination of silver's (100) and (110) surfaces. In the Ag(100) surface, the hollow site is the…

The initial stages of silver fluorination: a scanning tunneling microscopy investigation
Jazmín Aragón Sánchez, Antonio Caporale, Ilya Degtev +7
We use low-temperature scanning tunneling microscopy (LT-STM) to characterize the early stages of silver fluorination. On Ag(100), we observe only one adsorbate species, which show…
