Dynamics of phase separation of metastable crystal surfaces by surface diffusion: A phase-field study
T Philippe - Physical Review E, 2024 - APS
A new phase-field approach is designed to model surface diffusion of crystals with strongly
anisotropic surface energy. The model can be shown to asymptotically converge toward the …

A regularized phase-field model for faceting in a kinetically controlled crystal growth
T Philippe, H Henry, M Plapp - Proceedings of the …, 2020 - royalsocietypublishing.org
At equilibrium, the shape of a strongly anisotropic crystal exhibits corners when for some
orientations the surface stiffness is negative. In the sharp-interface problem, the surface free …

Regularized anisotropic motion-by-curvature in phase-field theory: Interface phase separation of crystal surfaces
T Philippe, H Henry, M Plapp - Physical Review E, 2022 - APS
The kinetic equation for anisotropic motion-by-curvature is ill posed when the surface energy
is strongly anisotropic. In this case, corners or edges are present on the Wulff shape, which …
