Kinetic models of Quantum Size Effect-directed nanocluster self-assembly in atomic corrals

TL;DR

This paper presents two kinetic models explaining how quantum size effects influence nanocluster self-assembly in atomic corrals, highlighting the impact of electronic density variations on the process.

Contribution

It introduces simple kinetic models for nanocluster self-assembly driven by quantum size effects, considering different adsorption regimes at varying temperatures.

Findings

Electronic local density variations hinder self-assembly at high temperatures.

Two regimes of self-assembly are characterized: adsorption and adsorption-diffusion.

Models explain the temperature-dependent behavior of nanocluster formation.

Abstract

Two simple kinetic models of Quantum Size Effect-directed nanocluster self-assembly in circular atomic corrals are discussed. The models correspond to an adsorption (either a physisorption or a chemisorption) and an adsorption-diffusion regimes that are typical at low and high temperatures, respectively. Small magnitudes of a variation of the electronic local density of states is shown to be the prime factor that impedes self-assembly in the latter regime.
