CRUCIBLE FOR PRODUCTION OF MONOCRYSTALS BY THE HANGING DROP METHOD

摘要

Crucible can be used for the continuous manufacture of single crystals of form predetermined as well as the deposition of crystalline silicon thin film on a substrate of graphite by the method of the hanging drop, comprising at its lower part of one or more capillary orifices having a height which is greater or the same at the level of retention in the capillary of the molten material used to manufacture the single crystal or constituting the film deposit at the temperature and pressure regarded, characterizes in that the bottom of the crucible is a screen covers by a conical supports by means of feet resting on the bottom of the crucible. / p & & p & the crucible of the invention makes it possible to obtain crystals having a high dimensional regularity and does not contain any bubbles or stone. / p & & p & the single crystals prepared according to the invention find numerous applications in jewelry, in electronic timepieces and
