“…The work [1,[3][4][5][6][7][8][9][10] covers many topics, such as hot zone design, defect control, modeling technique and so on, and has greatly speeded up the pace to achieve high-quality crystals in experiments and industries. The shape of the grown crystal is usually cylindrical due to the natural characteristics of the Cz technique, which is advantageous for the growth of crystals with uniform properties.…”
