Implication

Morphological analysis demonstrates facet formation dependence on interface curvature in garnet crystals, highlighting a geometric parameter for growth control.

Key Points

  • To analyze how {110} and {211} facets form during the growth of rare-earth aluminium garnet crystals across multiple crystallographic directions.
  • Evaluated the occurrence and spatial distribution of {110} and {211} type facets along distinct crystallographic growth orientations.
  • Formulated a geometric relationship comparing crystal diameter (D) to the curvature radius of the spherical growth interface (R).
  • The dimensionless parameter D/2R accurately predicts and characterizes both the total number and the spatial configuration of emerging facets.
  • Variations in the spherical growth interface curvature directly govern facet formation across different crystallographic axes.
