Weierstrass Institute Berlin (WIAS)

Description

The Leibniz Institute for Crystal Growth is developing affordable crystal growth technique for pure silicon crystals. We provide numerical input to understand how impurities introduced during the growth process can be measured. To this end, we replace inflexible blackbox code with a physics preserving FV discretization to tackle unsolved problems such as slow convergence for low doping densities, parameter reduction and suitable anisotropic grids.
