Mass transport of adsorbates near a discontinuous structural phase transition
E. Granato, S. C. Ying, K. R. Elder +1
We study the mass transport dynamics of an adsorbed layer near a discontinuous incommensurate striped-honeycomb phase transition via numerical simulations of a coarse-grained model…
Minimum energy path for the nucleation of misfit dislocations in Ge/Si(001) heteroepitaxy
Oleg Trushin, Emile Maras, Alexander Stukowski +4
A possible mechanism for the formation of a 90° misfit dislocation at the Ge/Si(001) interface through homogeneous nucleation is identified from atomic scale calculations where a m…
Evolution of Non-Equilibrium Profile in Adsorbate Layer under Compressive Strain
E. Granato, S. C. Ying
We investigate the time evolution of an initial step profile separating a bare substrate region from the rest of the compressively strained adsorbate layer near a commensurate to i…
Dynamical transitions and sliding friction of the phase-field-crystal model with pinning
J. A. P. Ramos, E. Granato, S. C. Ying +3
We study the nonlinear driven response and sliding friction behavior of the phase-field-crystal (PFC) model with pinning including both thermal fluctuations and inertial effects. T…
Two Approaches to Dislocation Nucleation in the Supported Heteroepitaxial Equilibrium Islanding Phenomenon
J. Jalkanen, O. Trushin, K. Elder +3
We study the dislocation formation in 2D nanoscopic islands with two methods, the Molecular Static method and the Phase Field Crystal method. It is found that both methods indicate…
Equilibrium Shape and Size of Supported Heteroepitaxial Nanoislands
J. Jalkanen, O. Trushin, E. Granato +2
We study the equilibrium shape, shape transitions and optimal size of strained heteroepitaxial nanoislands with a two-dimensional atomistic model using simply adjustable interatomi…
