Fig. 8: Cyclic a-Si ↔ Si I, a-Si ↔ Si IV, and Si I ↔ Si IV phase transformations in the shear band during the shear loading.

Snapshots of cubic diamond, hexagonal diamond, and amorphous phases are presented in (A–G), corresponding to the points in the shear stress-strain curve in (H). For point F in (H), the stress distribution is also presented.
