Float-zone crystal growth of bismuth germanate and numerical simulation
Bismuth germanium Oxide BGO ( Bi 12 GeO 20) single crystals are known to have great potential for technological applications in solid-state devices. Our work involves crystal growth of this material from the melt using a float-zone (FZ) technique in both terrestrial and microgravity environments. Th...

20) single crystals are known to have great potential for technological applications in solid-state devices. Our work involves crystal growth of this material from the melt using a float-zone (FZ) technique in both terrestrial and microgravity environments. The ground-based (normal gravity) experiments are presently being carried out, and the ensuing results will be used to optimize the microgravity experiments which will be executed aboard the SPACEHAB Shuttle mission scheduled for April 1994. The crystal growth technique that is being developed requires BGO feed rods of high quality. The methods developed to produce these, and the important float zone parameters such as temperature, translation rate and uniformity of radial heat distribution of the furnace for the crystal growth are discussed. An analysis of the effect of shape and convection patterns on the materials, using numerical simulation to compare the theoretical predictions with the experimental results is also presented. |
