WebApr 10, 2024 · During single crystal growth, travelling velocity of the ampoule in the downward direction was fixed at 1 cm/day, corresponding to 14 days to complete the growth experiment. The rod-shaped ingot thus obtained was cut into wafers with thicknesses of ca. 1.0 mm. ... The wafer sample obtained by cutting the ingot diagonal to … WebOnce the system reaches proper conditions for crystal growth, the seed crystal slowly lifts out of the melt. Growth begins with a rapid pulling of the seed crystal. This minimizes the number of crystal defects within the seed at the beginning of the growing process. Slicing.
