Fig. 2: High-resolution transmission electron microscopy images of strain-induced amorphous bands in Si I.

a Amorphous band obtained within larger Si IV band after its appearance in Si I 〈111〉 nanopillar under uniaxial compression. The scale bar is 5 nm. Residual nanosized Si IV clusters are marked by dotted blue circles. Reproduced with permission from17. b, c Amorphous shear bands in Si I shocked using a high energy laser. Reproduced with permission from58 and23, respectively.
