Two-dimensional simulations are used to explore topological transitions that occur during the formation of films grown from grains that are seeded on substrates. This is done for a relatively large range of the initial value Φs of the grain surface fraction Φ. The morphology of porous films is captured at the transition when grains connect to form a one-component network using newly developed raster-free algorithms that combine computational geometry and network theory. Further insight on the…

Simulation of faceted film growth in three dimensions: microstructure, morphology and texture
A series of simulations of the growth of polycrystalline, faceted films from randomly oriented nuclei in two spatial dimensions was performed. The simulations track the motion of all corners where
Numerical model of solid phase transformations governed by nucleation and growth : Microstructure development during isothermal crystallization
A simple numerical model which calculates the kinetics of crystallization involving randomly distributed nucleation and isotropic growth is presented. The model can be applied to different thermal
Impact of pore distribution characteristics on percolation threshold based on site percolation theory
Abstract In order to better simulate the porous media with different pore distribution characteristics, this paper introduced a pore distribution factor m (m represents the randomly generated pore
Separation of intra- and intergranular magnetotransport properties in nanocrystalline diamond films on the metallic side of the metal-insulator transition
A systematic study on the morphology and electronic properties of thin heavily boron-doped nanocrystalline diamond (NCD)films is presented. The films have nominally the same thickness ( 150nm) and
Synthesis of thin films with highly tailored microstructures
ABSTRACT We report a new methodology to synthesize thin films with exceptional microstructural control via systematic, in-situ seeding of nanocrystals into amorphous precursor films. When the
Spin‐seeding approach for diamond growth on large area silicon‐wafer substrates
The growth of polycrystalline diamond by chemical vapor deposition requires a substrate pre-treatment in order to achieve thin, high-quality, and pore-free diamond layers. Seeding the substrate by
On the grain size-thickness correlation for thin films
Abstract A meta-analysis of published data in combination with measurements on Al, Cu, CuO, CoCrCuFeNi, Ni90Cr10, TiN, and V sputter deposited thin films, demonstrates that the grain size is
Grain boundary networks: Scaling laws, preferred cluster structure, and their implications for grain boundary engineering
Abstract Within the context of grain boundary engineering, where grain boundaries are classified as special vs. general, grain boundary networks are known to have non-random topologies and
Nucleation and growth of orbital ordering
It is reported that the dynamics of a phase transition associated with an ordering of d orbitals in a vanadate exhibits a clear nucleation-growth behavior and that the interfacial energy between the orbital-ordered and -disordered phases dominated by the orbitals-spin coupling can be experimentally obtained.
Grain Boundary Complexions
Abstract Grain boundaries exhibit phase-like behavior in which their structure, chemistry and properties may change discontinuously at critical values of thermodynamic parameters such as temperature,
