Experimental ground-based Bridgman CdTe growth in NASA's advanced automated directional solidification furnaceThe role of gravity-induced phenomena in bulk CdTe crystal growth is studied with emphasis placed on the negative effects of buoyancy-driven convection, container effects, and hydrostatic pressure. An earth-bound crystal growth data base utilizing NASA's prototype advanced automated directional solidification furnace is described. Growth procedures that can be employed in a microgravity environment aboard the Space Shuttle or Space Station are presented. It is found that NASA's directional solidification furnace can produce Bridgman-type CdTe and has the potential for producing it in space.
