Irreversible nucleation in molecular beam epitaxy: From theory to experiments
Paolo Politi, Claudio Castellano
Recently, the nucleation rate on top of a terrace during the irreversible growth of a crystal surface by MBE has been determined exactly. In this paper we go beyond the standard mo…
Dipolar interaction between two-dimensional magnetic particles
Paolo Politi, Maria Gloria Pini
We determine the effective dipolar interaction between single domain two-dimensional ferromagnetic particles (islands or dots), taking into account their finite size. The first cor…
The process of irreversible nucleation in multilayer growth. II. Exact results in one and two dimensions
Paolo Politi, Claudio Castellano
We study irreversible dimer nucleation on top of terraces during epitaxial growth in one and two dimensions, for all values of the step-edge barrier. The problem is solved exactly…
The process of irreversible nucleation in multilayer growth. I. Failure of the mean-field approach
Paolo Politi, Claudio Castellano
The formation of stable dimers on top of terraces during epitaxial growth is investigated in detail. In this paper we focus on mean-field theory, the standard approach to study nuc…
