Fig. 1

A Illustration of the stacking and cutting procedures for fabricating BNNS-TIMs, and a schematic depiction of the microstructure of the filler arrangement. B–F SEM images of BNNS-TIMs: B BNNS in the bulk material; C view of the machined surface; D–F side-view SEM images of BNNSs near the cut surfaces of specimens with 50, 70, and 90 wt% loadings. The scale bars in B and C are 5 μm, and those in D–F are 20 μm. G XRD patterns of specimens with loadings of 50–90 wt.%. X-ray-1 denotes X-rays incident on the cut surfaces of specimens and gives the BNNS-1 patterns, and X-ray-2 refers to those incident on the cross-sections of specimens and gives the BNNS-2 patterns.
