Figure 2
(a) Photographs of the top view of a GdBCO crystal induced by two sets of (110)/(110) arranged double-seeds. From the left set, two crystals with concave joints independently propagated at a normal rate, while the right-set-induced crystals combined into a large single crystal with a rapid-growth zone, as amplified in the inset (white diamond frame). (b) Schematic illustrations of growth modes corresponding to imprecisely and precisely (110)/(110) arranged double-seeding. |
