Fundamental Studies of Diamond Growth and Surface Reactions
Abstract
This report summarizes the research carried out during the period March 1991 through May 1994 at Rockwell Science Center under ONR contract No. Nooo14-91-C-0048. This contract was part of the ONR directed effort on the development of polycrystalline diamond as an optical material. A primary focus of the research was investigating the relationships between the microstructure of polycrystalline diamond and its optical and mechanical properties. The program also involved a considerable effort in the development of characterization techniques for observing the fundamental properties of thick and thin diamond films. A secondary goal of the research was the investigation of the surface reactions of diamond to evaluate their potential for reactive polishing applications. Polishing is critical not only to the ultimate application of diamond as an optical material, but also to the characterization of its detailed microstructure. Also included in this program was an additional task, funded by the Naval Air Warfare Center Aircraft Division (NAWCAD) at Warminster, PA. The additional task was to devise a methodology for bonding diamond with an integral gradient index antireflective surface (moth-eye) to germanium and zinc sulfide and to provide samples of the bonded composites to NAWCAD for liquid jet impact testing.
