Device for the solidification and for the continuous monitoring of the crystal growth

摘要

The invention concerns a device for the solidification and continuous control of crystal growth in an electrically conductive doped material or alloy, based on a liquid or a molten bath, for continuously monitoring crystal growth in said doped material or alloy, in particular for continuously monitoring the dope content in the doped material or the alloyed element content in the alloy. The device is characterised in that it has two cavities using the "Seebeck Monogradient" process whereby the means for electrically short circuiting a first liquid of the non-doped material or the pure unalloyed element in thermal equilibrium with a first solid thereof, and a second liquid of said doped material or of said alloy in thermal equilibrium with a second solid thereof, consist in an isothermal and conductive passage with reduced dimension, connecting the two cavities.
