Quantum size effects of Pb overlayers at high coverages
A. Ayuela, E. Ogando, N. Zabala
We have studied Pb thin films as a function of the thickness up to 60 monolayers (MLs) using ab initio first principles and model calculations. Magic heights corresponding to a mod…
Restored quantum size effects of Pb overlayers at high coverages
A. Ayuela, E. Ogando, N. Zabala
Abnormally large stability of Pb nanostructures grown on metallic or semiconductor substrates has been observed even for heights of about 30 monolayers. Using both density-function…
Sensitiveness of the ratio between monovacancy and bulk positron lifetimes to the approximations used in the calculations: Periodic behaviour
J. M. Campillo-Robles, E. Ogando, F. Plazaola
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for…
Positron lifetime calculation of the elements of the periodic table
J. M. Campillo Robles, E. Ogando, F. Plazaola
Theoretical positron lifetime values have been calculated systematically for most of the elements of the Periodic Table. Self-consistent and non-self-consistent schemes have been u…
Quantum size effects in Pb islands on Cu(111): Electronic-structure calculations
E. Ogando, N. Zabala, E. V. Chulkov +1
The appearance of "magic" heights of Pb islands grown on Cu(111) is studied by self-consistent electronic structure calculations. The Cu(111) substrate is modeled with a one-dimens…
