The bridgman method
Did you know?
The Bridgman–Stockbarger method, or Bridgman–Stockbarger technique, is named after Harvard physicist Percy Williams Bridgman (1882–1961) and MIT physicist Donald C. Stockbarger (1895–1952). The method includes two similar but distinct techniques primarily used for growing boules (single-crystal ingots), but which can be used for solidifying polycrystalline ingots as well. 網頁It may be noted that the Bridgman method is one of the most popular methods of crystal growth because it is very easy to perform in a vacuum and in an inert atmosphere [26, …

網頁Bridgman method The variation with temperature of n and for an undoped GaAs crystal grown by the horizontal Bridgman method is shown in Fig. 3. The parameters that give the best fit to Eq. (12) are also shown. The power of this method is illustrated by the small probable errors in the fitted parameters, i.e., less than 15% for Nd and less than 1% for ED0.
