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…
Bound states in two-dimensional shielded potentials
I. Nagy, M. J. Puska, N. Zabala
We study numerically the existence and character of bound states for positive and negative point charges shielded by the response of a two-dimensional homogeneous electron gas. The…
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…
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…
