Figure 5: TEM images of SiCN/BN heterostructure.

(a) A typical view of a single SiCN−BN core‒shell nanostructure. (d) HRTEM images of SiC core. (b,c) and (e) The bright field images of SiC(N) nanowires wrapped by BN multilayers at different position, respectively. (f) Apart of bright field images of (c). Inset showed bright field images of SiCN–BN core–shell nanostructures in distinct amplifications.
