WebMar 31, 2024 · We report growth of single-crystal Cd0.9Zn0.1Te ingots while using the pressure-controlled Bridgman method. The Cd pressure was controlled during growth to suppress its evaporation from the melt and reduce the size of Te inclusions in the as-grown crystals. The accelerated crucible rotation technique (ACRT) was used to suppress … WebJun 4, 2024 · So the technique is called the encapsulated Czochralski technique. So here is a figure of the Czochralski Growth Tower. There is a person here, it's a pretty big tower. And here on the right is a photograph of the ingot of piece of single crystal in wafer. And you would basically chop once you make this ingot, then you would cut these.
