Islands in the Stream: Electromigration-Driven Shape Evolution with Crystal Anisotropy
Philipp Kuhn, Joachim Krug
We consider the shape evolution of two-dimensional islands on a crystal surface in the regime where mass transport is exclusively along the island edge. A directed mass current due…
Introduction to Step Dynamics and Step Instabilities
Joachim Krug
This paper provides an elementary introduction to the basic concepts used in describing epitaxial crystal growth in terms of the thermodynamics and kinetics of atomic steps. Select…
Step bunching during Si(001) homoepitaxy caused by the surface diffusion anisotropy
J. Myslivecek, C. Schelling, F. Schaffler +4
Scanning tunneling microscopy experiments show that the unstable growth morphology observed during molecular beam homoepitaxy on slightly vicinal Si(001) surfaces consists of strai…
Effects of atomic interactions in two component submonolayer growth
Miroslav Kotrla, Joachim Krug
We discuss effects of the different chemical bondings on the island morphology and on the island density scaling in two-component submonolayer growth. Different regimes depending o…
Effects of adsorbates on submonolayer growth
Miroslav Kotrla, Joachim Krug, Pavel Smilauer
The effects of adsorbates on nucleation and growth of two-dimensional islands is investigated by kinetic Monte Carlo simulations and rate equation theory. The variation of island m…
Second layer nucleation and the shape of wedding cakes
J. Krug, P. Kuhn
The rate of second layer nucleation -- the formation of a stable nucleus on top of a two-dimensional island -- determines both the conditions for layer-by-layer growth, and the siz…
