Figure 6. Distribution of GBs at the final sintering stage for 15 nm NPs with tilted misorientation angles of (A) 36.87^o, (B) 53.15^o for Ag NPs, and (C) 36.87^o, (D) 53.15^o for Cu NPs. Two sintering temperatures of 50%T_m and 70%T_m are included. The green arrows point to GBs. See Supplementary Materials for animations of selected key events. GBs: Grain boundaries; NPs: nanoparticles; T_m: bulk melting points.
