Advancing single-atom catalysts: engineered metal-organic platforms on surfaces
Amogh Kinikar, Xiushang Xu, Takatsugu Onishi +10
Recent advances in nanomaterials have pushed the boundaries of nanoscale fabrication to the limit of single atoms (SAs), particularly in heterogeneous catalysis. Single atom cataly…
How orbitals and oxidation states determine apparent topographies in scanning tunneling microscopy: the case of fluorine on silver surfaces
Adrián Gómez Pueyo, JazmÃn 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…
Synergistic effect of oxygen and water on the environmental reactivity of 2D layered GeAs
Luca Persichetti, Giacomo Giorgi, Luca Lozzi +4
We investigated the reactivity of layered GeAs in the presence of oxygen and/or water using synchrotron-based X-ray photoelectron spectroscopy and ab initio calculations.
Intersubband transition engineering in the conduction band of asymmetric coupled Ge/SiGe quantum wells
Luca Persichetti, Michele Montanari, Chiara Ciano +9
: n-type Ge/SiGe asymmetric-coupled quantum wells represent the building block of a variety of nanoscale quantum devices, including recently proposed designs for a silicon-based TH…
Tuning the doping of epitaxial graphene on a conventional semiconductor via substrate surface reconstruction
Miriam Galbiati, Luca Persichetti, Paola Gori +8
Combining scanning tunneling microscopy and angle-resolved photoemission spectroscopy, we demonstrate how to tune the doping of epitaxial graphene from p to n by exploiting the str…
Magnetic properties of metal-organic coordination networks based on 3d transition metal atoms
MarÃa Blanco-Rey, Ane Sarasola, Corneliu Nistor +8
The magnetic anisotropy and exchange coupling between spins localized at the positions of 3d transition metal atoms forming two-dimensional metal-organic coordination networks (MOC…
