Dimerization of Ag adatoms on Si(100) at surprisingly low temperature due to adatom migration on top of Si-dimer rows
Alejandro Peña-Torres, Michail Stamatakis, Hannes Jónsson
The puzzling experimental observations of Ag addimer formation on the Si(100) surface upon vapor deposition at low temperature, even as low as 140 K, reported by Huang et al. [Phys…
Quantum tunnelling driven H formation on graphene
Erxun Han, Wei Fang, Michail Stamatakis +2
It is commonly believed that it is unfavourable for adsorbed H atoms on carbonaceous surfaces to form H without the help of incident H atoms. Using ring-polymer instanton theor…
Indirect Mechanism of Au adatom Diffusion on the Si(100) Surface
Alejandro Peña-Torres, Abid Ali, Michail Stamatakis +1
Calculations of the diffusion of a Au adatom on the dimer reconstructed Si(100)-2x1 surface reveal an interesting mechanism that differs significantly from a direct path between op…
Periodic Trends in Adsorption Energies Around Single-Atom Alloy Active Sites
Julia Schumann, Yutian Bao, Ryan T. Hannagan +3
Single-Atom Alloys (SAAs) are a special class of alloy surface catalysts that offer well defined, isolated active sites in a more inert metal host. The dopant sites are generally a…
