Temperature-Dependent Morphology Evolution of Boron Nitride and Boron Carbonitride Nanostructures

Figure 8

Sketch growth model of BN one-dimensional nanostructure. (A) BN pathways feeding BN growth via (i) impingement of BN flux into the BN surface and surface diffusion over crystal to the BN edge and (ii) direct impingement of B/N into the catalyst alloy droplet and bulk diffusion through the droplet to the BN edge. (B-D) Growth process varied with increasing temperature. (ʋ_s: surface diffusion rate, ʋ_b: bulk diffusion rate).
