Preparation, characterization and application of nanocrystalline diamond films

The preparation, characterization and application of nanocrystalline diamond films have become a new "hot point" in the development of diamond films prepared by chemical vapor deposition. A review is presented of the pioneering works of Gruen et al. on nano－diamond film preparation in a hydrogen depleted environment, and comparisons are made with nano－diamond films deposited in a hydrogen－rich environment. Potential applications of these films are discussed.
