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…
Tracking interfacial changes of graphene/Ge(110) during in-vacuum annealing
L. Camilli, M. Galbiati, L. Di Gaspare +9
Graphene quality indicators obtained by Raman spectroscopy have been correlated to the structural changes of the graphene/Germanium interface as a function of in-vacuum thermal ann…
Second harmonic generation in germanium quantum wells for nonlinear silicon photonics
Jacopo Frigerio, Chiara Ciano, Joel Kuttruff +12
Second-harmonic generation (SHG) is a direct measure of the strength of second-order nonlinear optical effects, which also include frequency mixing and parametric oscillations. Nat…
THz intersubband electroluminescence from n-type Ge/SiGe quantum cascade structures
David Stark, Muhammad Mirza, Luca Persichetti +15
We report electroluminescence originating from L-valley transitions in n-type Ge/SiGe quantum cascade structures centered at 3.4 and 4.9 THz with a line broadenin…
