a A Σ3{112} ITB in another Au nanocrystal. Pulses of (1.0 V, 3 ns) were sequentially applied perpendicularly to the CTB. M and T represent the matrix and twin in Au nanocrystal, respectively. The green arrow indicates the direction of the electrical current. b–e Dynamic snapshots showing the non-directional migration of the ITB under electrical pulses. f Migration displacements of the ITB. The red and blue arrows represent the migration distance and direction under electropulsing and relaxation, respectively. The black dash lines represent the intervals between pulses.
