A semiempirical quantum approach to possible structures of copper electrodeposits at submonolayer and monolayer levels on Pt(100) and Pt(111) clusters
The development and reconstruction of surface structures formed by underpotential deposition (UPD) of Cu atoms on Pt(100) and Pt(111) clusters are approached through extended Hückel molecular orbital (EHMO) calculations applied to a statistical Cu atom deposition. These results allow us to obtain a...

| Sumario: | The development and reconstruction of surface structures formed by underpotential deposition (UPD) of Cu atoms on Pt(100) and Pt(111) clusters are approached through extended Hückel molecular orbital (EHMO) calculations applied to a statistical Cu atom deposition. These results allow us to obtain a qualitative description of the different stable configurations of Cu atoms on the Pt cluster surfaces in terms of the corresponding binding energies. |
