摘要：

Systematic studies of crystal growth of benzophenone by the Czochralski method and characterizations of dislocations in the grown crystals were performed. The dislocations introduced during the crystal growth were observed using X-ray topography. The characteristics of these dislocations were determined by an invisibility condition of dislocation images. Furthermore they were analyzed by a minimum energy criterion of preferred directions of dislocation lines. From these characterizations, a shorter Burgers vector c[001] was found to be generated in crystals grown along directions of [001], [010] and [100]. Several longer Burgers vectors were also found to exist in spite of their higher dislocation energies. These characteristics of grown-in dislocations are
