Explanation
This case aims to model an experiment of polycristalline silicon growth from a single seed. This experiment is available in refs [1,2] (see below). During its growth, the initial grain develops two facets with both lateral borders of the simulation domain. Multiple grains in twin relationship nucleate on these facets. This observation corresponds to the successive twinning process usually observed during silicon growth.
The main numerical parameters of this simulation are the mean activation undercooling, its standard deviation and the growth kinetic of the {111} facets. These parameters are determined using the in situ experimental observations available in refs [1,2] and are such as:
| Parameter | Description | Value |
|---|---|---|
| $\Delta{T}^{\mu}_{\{111\}}$ | Mean activation undercooling for {111} facets | 2 K |
| $\Delta{T}^{\sigma}_{\{111\}}$ | Standard deviation | 0.1 K |
| $\Delta{T}^{E}_{N,T}$ | Twins nucleation undercooling at the edges of the domain | 2.1 K |
| $\Delta{T}^{B}_{N,T}$ | Twins nucleation undercooling at grains boundaries grooves | 1.8 K |
| $v^{c}_{\{111\}}$ | Growth kinetic of the {111} facets | 9 µm/s |
