A sharp-interface approach for simulating solid-state dewetting of thin films with double-bubble structure
Meng Li, Nan Wang, Ruofan Zhao +1
We develop a sharp-interface model for solid-state dewetting of double-bubble thin films using an energy variational approach based on a newly proposed interfacial energy. This mod…
Willmore regularized sharp-interface model for strongly anisotropic solid-state dewetting with axisymmetric geometry: modeling and simulation
Meng Li, Chunjie Zhou
In this work, we consider the three-dimensional solid-state dewetting with strongly anisotropic surface energy, assuming an axisymmetric morphology of the thin film. However, when…
Solid-state dewetting of axisymmetric thin film on axisymmetric curved-surface substrates: modeling and simulation
Zhenghua Duan, Meng Li, Chunjie Zhou
In this work, we consider the solid-state dewetting of an axisymmetric thin film on a curved-surface substrate, with the assumption that the substrate morphology is also axisymmetr…
Energy-stable parametric finite element approximations for regularized solid-state dewetting in strongly anisotropic materials
Meng Li, Chunjie Zhou
In this work, we aim to develop energy-stable parametric finite element approximations for a sharp-interface model with strong surface energy anisotropy, which is derived from the…
Structure-preserving parametric finite element methods for simulating axisymmetric solid-state dewetting problems with anisotropic surface energies
Meng Li, Chunjie Zhou
Solid-state dewetting (SSD), a widespread phenomenon in solid-solid-vapor system, could be used to describe the accumulation of solid thin films on the substrate. In this work, we…
