Mass and Heat Transport in BS and EFG Systems

Abstract

In this chapter several mathematical models describing processes which take place in the Bridgman–Stockbarger (BS) and edge-defined film-fed growth (EFG) systems are presented. Predictions are made concerning the impurity repartition in the crystal in the framework of each of the models. First, a short description of the real processes which are modeled is given, along with the equations, boundary conditions, and ini-tial values defining the mathematical model. After that, numerical results obtained by computations in the framework of the model are provided, mak-ing a comparison between the computed results and those obtained in other models, and with the experimental data.
