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…

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…
