Nonlinear dynamics of surface steps
Joachim Krug
This is a review of recent theoretical work on complex dynamical behavior of steps on crystal surfaces. The first part of the article is devoted to the electromigration-driven moti…
Spiral Growth and Step Edge Barriers
A. Redinger, O. Ricken, P. Kuhn +4
The growth of spiral mounds containing a screw dislocation is compared to the growth of wedding cakes by two-dimensional nucleation. Using phase field simulations and homoepitaxial…
Spiral growth, two-dimensional nucleation, and the Ehrlich-Schwoebel effect
Joachim Krug
Frank's prediction of the spiral growth mode in 1949 defined a pivotal moment in the history of crystal growth. In recent decades the topic has received less attention, and instead…
Morphological stability of electromigration-driven vacancy islands
Frank Hausser, Philipp Kuhn, Joachim Krug +1
The electromigration-induced shape evolution of two-dimensional vacancy islands on a crystal surface is studied using a continuum approach. We consider the regime where mass transp…
Kinetic Monte Carlo simulations of oscillatory shape evolution for electromigration-driven islands
Marko Rusanen, Philipp Kuhn, Joachim Krug
The shape evolution of two-dimensional islands under electromigration-driven periphery diffusion is studied by kinetic Monte Carlo (KMC) simulations and continuum theory. The energ…
Complex shape evolution of electromigration-driven single-layer islands
Philipp Kuhn, Joachim Krug, Frank Hausser +1
The shape evolution of two-dimensional islands through periphery diffusion biased by an electromigration force is studied numerically using a continuum approach. We show that the i…
