Multi-nanolayered VO2/Sapphire Thin Film via Spinodal Decomposition

Monolayer pattern evolution via substrate strain-mediated spinodal decomposition.

Investigations of octylsilane (C8H17SiH3) monolayer pattern formation on Au(111) are reported. Scanning tunneling microscopy data display the evolution of a approximately 6 nm scale pattern of interwoven features concomitant with ejection of surface Au atoms and relaxation of the Au(111) 23xsqrt[3] surface reconstruction. Numerical simulations suggest the surface dynamics are governed by a subs...

Spinodal Decomposition for Multi-component Cahn-hilliard Systems

We consider the initial stage phase separation process in multi-component CahnHilliard systems through spinodal decomposition. Relying on recent work of MaierPaape and Wanner we establish the existence of certain dominating subspaces determining the behavior of most solutions originating near a spatially homogeneous state. It turns out that depending on the initial concentrations of the alloy c...

Colloid-in-liquid crystal gels formed via spinodal decomposition.

We report that colloid-in-liquid crystal (CLC) gels can be formed via a two-step process that involves spinodal decomposition of a dispersion of colloidal particles in an isotropic phase of mesogens followed by nucleation of nematic domains within the colloidal network defined by the spinodal process. This pathway contrasts to previously reported routes leading to the formation of CLC gels, whi...

Parallel Spinodal Decomposition

Spinodal decomposition encompasses the ordering dynamics of thermodynamically unstable phases. An example of spinodal decomposition is the separation of the metals in a binary alloy. Because physicists have been unable to develop a fully coherent, consistent , and calculable theory on spinodal decomposition, computational studies have served as valuable sources of information. However, since th...
