Kinetic model of II-VI(001) semiconductor surfaces: Growth rates in atomic layer epitaxy
T. Volkmann, M. Ahr, M. Biehl
We present a zinc-blende lattice gas model of II-VI(001) surfaces, which is investigated by means of Kinetic Monte Carlo (KMC) simulations. Anisotropic effective interactions betwe…
Kinetic Monte Carlo Simulations of dislocations in heteroepitaxial growth
F. Much, M. Ahr, M. Biehl +1
We determine the critical layer thickness for the appearance of misfit dislocations as a function of the misfit between the lattice constants of the substrate and the adsorbate fro…
The influence of the crystal lattice on coarsening in unstable epitaxial growth
M. Ahr, M. Biehl, M. Kinne +1
We report the results of computer simulations of epitaxial growth in the presence of a large Schwoebel barrier on different crystal surfaces: simple cubic(001), bcc(001), simple he…
Singularity spectra of rough growing surfaces from wavelet analysis
Martin Ahr, Michael Biehl
We apply the wavelet transform modulus maxima (WTMM) method to the analysis of simulated MBE-grown surfaces. In contrast to the structure function approach commonly used in the lit…
Weight decay induced phase transitions in multilayer neural networks
M. Ahr, M. Biehl, E. Schloesser
We investigate layered neural networks with differentiable activation function and student vectors without normalization constraint by means of equilibrium statistical physics. We…
A simple model of epitaxial growth
M. Biehl, W. Kinzel, S. Schinzer
A discrete solid-on-solid model of epitaxial growth is introduced which, in a simple manner, takes into account the effect of an Ehrlich-Schwoebel barrier at step edges as well as…
