The report is divided into two parts. The first part is to grow boron nitride through the easy-to-obtain sapphire substrate, and the second part is to use nickel-plated substrate (Ni/SiO2/Si). In the first part, there are two processes for growing boron nitride. One is to open boron cell and N-plasma source at the same time. Another is to open boron cell and then open N-plasma source via droplet epitaxy. In the second part, there are three series. The first series is different substrate temperature, the second series is to change the temperature of boron cell, and the third series is to compare different process. All sample were observed by Reflective High Energy Electron Diffraction, then analyzed by Raman and X-ray Photoelectron Spectroscopy, and the morphology was observed by Field-Emission Scanning Electron Microscopy and Atomic Force Microscopy. This study found better boron nitride formation by droplet epitaxy. When the substrate temperature increases or the boron source temperature increases, the crystallinity of boron nitride can be effectively increased. Ing-Song Yu 余英松 2019 學位論文 ; thesis 95 zh-TW |

This study found better boron nitride formation by droplet epitaxy. When the substrate temperature increases or the boron source temperature increases, the crystallinity of boron nitride can be effectively increased.
