An integrated strategy towards the high-yield fabrication ...

To further improve the yield, we incorporated CVD growth between ball-milling and sonification in this work. Ball-milling often employs BN as raw materials, but here we used the B 2 O 3 /B/BN mixtures as precursors to provide active boron sources for CVD growth. Nucleation and growth are key factors for nanocrystals formation in CVD system.
