Plasma, photon, and beam synthesis of diamond films and multilayered structures

Three major areas of fundamental research on diamond thin films have been carried out successfully during the last period 1989 to 1990. By controlling the nucleation process we have learned that very smooth and transparent films can be grown at low temperatures. We have carefully studied the chemistry of iron surfaces and learned how to nucleate and grow diamond films on them. In addition, we have devised a means of growing composite diamond film which is flexible. Diamond films can be doped to conduct electricity. We have made careful studies on the physical and optical properties of Boron doped diamond films.
