Abstract
An apparatus for use in solidification of a doped electrically conducting material and for use in monitoring said solidification is provided. The apparatus includes a first forming means for forming a liquid of undoped material in thermodynamic equilibrium with a solid of the undoped material, and a second forming means for forming a liquid of doped material in thermodynamic equilibrium with a solid of the doped material. Solidification of the conducting material occurs at a solidification interface between the doped liquid and the doped solid in the second forming means. In one preferred embodiment, the apparatus comprises a conductive bridge for short-circuiting the liquids.
