Floating Zone - an overview ScienceDirect Topics

Float-zone silicon is very pure silicon obtained by vertical zone melting. The process was developed at Bell Labs by Henry Theuerer in 1955 as a modification of a method developed by William Gardner Pfann for germanium. In the vertical configuration molten silicon has sufficient surface tension to keep the charge from separating. The major advantages is crucibleless growth that prevents conta… Witrynaprogressively enriched with these impurities as the crystal is being pulled.

Witryna1 lis 2011 · Nitrogen impurity was found to prevent generation of swirl and D-defects in FZ crystals. These observations may lead to understanding formation of microdefects. (Author abstract. WitrynaImpurities in the molten region tend to stay in the molten region rather than be incorporated into the solidified region, thus allowing a very pure single crystal region to be left after the molten region has passed. WitrynaFloating zone crystal growth is a containerless technique to purify crystals and alloys. The basic arrangement of this process is shown in Fig1. Since no crucible is required in this method it is possible to eliminate contamination from the container. dangeours beauty monica
