# Amorphous SrTiO₃ with 8 Å α-perovskite grains: each Voronoi cell is barely large enough to host one or two randomly-oriented TiO₆ motifs. Only a handful of full octahedra survive the boundaries; everywhere else is disordered oxygen connectivity. ## Parameters ```python cell.generate( shell_target, num_steps=300, grain_size=None, bond_weight=0.50, angle_weight=0.4, repulsion_weight=1.1, hard_core_scale=1.10, nonbond_push_scale=0.65, displacement_sigma=0.008, ) ``` ## Relaxation trajectory ## g3 distribution
