Numerical simulations of foam structure formation and destruction process were demonstrated using a phase field model. Two types of additional terms to control the cell size were introduced to the conventional multi-phase field model; one is to maintain the initial cell size, and the other is to adjust the size of neighboring cells to be equalized to each other. As a result, different types of foam structures were obtained according to the introduced effect of the extra terms. Destruction process was also simulated under simple assumptions; instantaneous bursts of cell wall occur intermittently at random sites, and the cell coarsening is accelerated when a certain time has passed. The intended variation was successfully observed, and the effectiveness of the model was confirmed.

Heteroepitaxially grown multilayered thin film structures have been attracted of great interest due to its potential applications in photovoltaic/light emitting/electronics devices. The thin film morphology plays an important role in enhancing its related physical properties. It is not easy to simulate the multi-layered thin film structures due to the influence of the interface/surface fluctuation. However, the phase field method, based on thermodynamics and Cahn-Hilliard diffusion model, can predict the thin film morphologies without tracking the interfaces. In this paper, a new phase field model was developed for predicting multi-layer structures with multi-order parameters. The morphologies with strain distributions of the quantum wells, quantum dots and buffer layers structures were investigated in the current study. We found that the strain distribution has a strong effect on the suface/interface morphologies in the multilayered structures. Some simulation results are consistent with experimental observations.
