Abstract: The effects of atomic hydrogen on the growth of nanodiamond films were explored under different conditions of preparation. It is believed hydrogen-poor is not the necessary factor for preparation of nanodiamond films. The mechanisms of atomic hydrogen and Ar are different between the condition of hydrogen-poor and hydrogen-rich. Substrate bias fixed, can promote the production of H+. H+ can etch sp2 carbon stronger than sp3 carbon, and can result in surfacspe defects. Therefore, the condition of hydrogen-rich will be assistant to the nucleation and growth of nanodiamond films.

Key words: atomic hydrogen, nanodiamond films, substrate bias, nucleation, growth
