Dislocation dynamics during the growth of silicon ribbon.

Examines the thermal viscoplastic stresses and the dislocation densities in silicon ribbon, using an iterative finite difference method. Description of the Haasen-Sumino material model; Factors that affect the mechanical behavior of silicon crystals; Information on the general constitutive equation for silicon; Details of the variations of the elastic and viscoplastic thermal stresses along the center line of the ribbon.
