Nuclearity of Copper Clusters on hBN/SiC Heterostructure Modulates Molecular Adsorption
Reza Khakpour, Arsalan Hashemi, Xiaoya Chang +3
Defect engineering can transform inert two-dimensional (2D) materials into chemically active and electronically tunable platforms by creating anchoring sites for metal atoms and cl…
Influence of dislocations in multilayer graphene stacks: A phase field crystal study
K. R. Elder, Zhi-Feng Huang, T. Ala-Nissila
In this work the influence of dislocations in multiplayer graphene stacks (up to six layers) is examined. The study is conducted through a recently developed Phase Field Crys…
Moiré patterns and inversion boundaries in graphene/hexagonal boron nitride bilayers
K. R. Elder, Zhi-Feng Huang, T. Ala-Nissila
In this paper a systematic examination of graphene/hexagonal boron nitride (g/hBN) bilayers is presented, through a recently developed two-dimensional phase field crystal model tha…
Evolution of temporal coherence in confined polariton condensates
M. Klaas, H. Flayac, M. Amthor +6
We study the influence of spatial confinement on the second-order temporal coherence of the emission from a semiconductor microcavity in the strong coupling regime. The confinement…
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…
Eighth-order phase-field-crystal model for two-dimensional crystallization
A. Jaatinen, T. Ala-Nissila
We present a derivation of the recently proposed eighth order phase field crystal model [Jaatinen et al., Phys. Rev. E 80, 031602 (2009)] for the crystallization of a solid from an…
Phase Field Crystal Study of Symmetric Tilt Grain Boundaries of Iron
A. Jaatinen, C. V. Achim, K. R. Elder +1
We apply the phase field crystal model to study the structure and energy of symmetric tilt grain boundaries of bcc iron in 3D. The parameters for the model are obtained by using a…
Nonlinear Driven Response of a Phase-Field Crystal in a Periodic Pinning Potential
C. V. Achim, J. A. P. Ramos, M. Karttunen +4
We study numerically the phase diagram and the response under a driving force of the phase field crystal model for pinned lattice systems introduced recently for both one and two d…
Minimum energy paths for dislocation nucleation in strained epitaxial layers
O. Trushin, E. Granato, S. C. Ying +2
We study numerically the minimum energy path and energy barriers for dislocation nucleation in a two-dimensional atomistic model of strained epitaxial layers on a substrate with la…
