Excitation of confined bulk plasmons in metallic nanoparticles by penetrating electron beams within a nonlocal analytical approach
Mattin Urbieta, Eduardo Ogando, Alberto Rivacoba +2
Using a linear hydrodynamic model, we theoretically investigate the interaction between penetrating electron beams and sub-5-nm metallic spherical nanoparticles. We derive an analy…
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…
Self-consistent study of electron confinement to metallic thin films on solid surfaces
E. Ogando, N. Zabala, E. V. Chulkov +1
We present a method for density-functional modeling of metallic overlayers grown on metallic supports. It offers a tool to study nanostructures and combines the power of self-consi…
