Fig. 1 Snapshots of simulating procedure. ( a ) The system consisted of a rigid indenter and a deformable substrate with a body-centred-cubic W (1 0 0) surface. The detailed geometry of the substrate was 127 × 10 × 32 nm in the x -, y -, and z -axis, respectively. The radius at upper and lower ... More
