also account for the observed formation of star and rod shaped FSDCs, and some of their more obvious morphological defects. Key words: diamond; five-fold symmetry; icosahedron; dodecahedrane; defect 1... and IDCs [16-19,22-24]. The formation of IDCs with five-fold symmetry has been explained in terms of three stacking errors during growth on different
for understanding mechanical, vibrational and dynamical properties in metallic glasses. Local five-fold symmetry was defined based on the ratio of pentagons to the total number of faces in a Voronoi cluster analyzed by Voronoi tessellation method. It is found that the plastic deformation prefer to be initiated in the regions with less degree of local five-fold symmetry(LFFS) and propagate gradually......
