Significance of czochralski technique
WebIII.A.2 Czochralski Growth. Czochralski growth, or crystal pulling, is the dominant commercial process for the growth of single crystals of silicon, compound semiconductors, metals, oxides, and halides. The Czochralski technique essentially consists of a crucible containing the material to be crystallized surrounded by a heater to melt the charge.
