Nanodiamond-related materials are widely investigated for many applications in mechanics, electronics and semiconductors due to the superior properties of hardness, thermal stability and wide energy band gap. However, the high cost of nanodiamond-related materials due to the low growth rate limits the commercialization. This book studies different approaches of preparing nanodiamond- related materials and analysis of material properties. Nano-Ni catalysts by one-step chemical reduction were used for the catalytic growth of nanodiamond films by Hot Filament CVD. Nitrogen- doped...
