Multi-Physics Modeling Of Phase Change Memory Operations in Ge-rich GeSbTe Alloys
Robin Miquel, Thomas Cabout, Olga Cueto +2
One of the most widely used active materials for phase-change memories (PCM), the ternary stoichiometric compound GeSbTe (GST), has a low crystallization temperature of…
Grand-potential phase field simulations of droplet growth and sedimentation in a two-phase ternary fluid
Werner Verdier, Alain Cartalade, Mathis Plapp
A methodology is built to model and simulate the dynamics of domain coarsening of a two-phase ternary liquid with an arbitrary phase diagram. High numerical performance is obtained…
Spinodal decomposition and domain coarsening in a multi-layer Cahn-Hilliard model for lithium intercalation in graphite
Antoine Cordoba, Marion Chandesris, Mathis Plapp
During the intercalation of lithium in layered host materials such as graphite, lithium atoms can move within the plane between two neighboring graphene sheets, but cannot cross th…
On topological defects in two-dimensional orientation-field models for grain growth
Bálint Korbuly, Mathis Plapp, Hervé Henry +3
Standard two-dimensional orientation-field based phase-field models rely on a continuous scalar field to represent crystallographic orientation. The corresponding order parameter s…
Nucleation of crystal surfaces with corner energy regularization
Thomas Philippe, Hervé Henry, Mathis Plapp
The thermodynamics of strongly anisotropic crystalline surfaces is analogous to that of a binary mixture exhibiting phase separation. On a metastable planar surface, formation of s…

In the literature, contradictory results have been published regarding the form of the limiting (long-time) grain size distribution (LGSD) that characterizes the late stage grain c…
Influence of interphase anisotropy on lamellar eutectic growth patterns
Supriyo Ghosh, Mathis Plapp
It is well documented in many experiments that crystallographic effects play an important role in the generation of two-phase patterns during the solidification of eutectic alloys.…
Current Induced Fingering Instability in Magnetic Domain Walls
Jon Gorchon, Javier Curiale, Andrejs Cebers +4
The shape instability of magnetic domain walls under current is investigated in a ferromagnetic (Ga,Mn)(As,P) film with perpendicular anisotropy. Domain wall motion is driven by th…
An orientation-field model for polycristalline solidification with a singular coupling between order and orientation
Hervé Henry, Jesper Mellenthin, Mathis Plapp
The solidification of polycrystalline materials can be modelled by orientation-field models, which are formulated in terms of two continuous fields: a phase field that describes th…
Tensorial mobilities for accurate solution of transport problems in models with diffuse interfaces
Matteo Nicoli, Mathis Plapp, Hervé Henry
The general problem of two-phase transport in phase-field models is analyzed: the flux of a conserved quantity is driven by the gradient of a potential through a medium that consis…
Unified derivation of phase-field models for alloy solidification from a grand-potential functional
Mathis Plapp
In the literature, two quite different phase-field formulations for the problem of alloy solidification can be found. In the first, the material in the diffuse interfaces is assume…
