Diamonds are the overachievers of the materials world. They can sustain incredibly high temperatures and electric fields. They also conduct heat better than any other material. These properties make them ideal for very specific applications. Currently, silicon dominates the electronics market. It’s used to make everything from your cell phone computer chip and laptop processor to microwave ovens. But as versatile as silicon is, there are certain areas where it falls flat.

MRS BULLETIN Diamond is a unique material that often exhibits extreme properties compared to other materials. Discovered about 30 years ago, the use of hydrogen in plasma-enhanced chemical vapor deposition (CVD) has enabled the growth and coating of diamond in film form on various substrate materials. CVD diamond research has been actively continued subsequently to develop new understanding and approaches for the growth and processing of this fascinating material. Currently, the study and development of diamond films has enabled a wide range of applications based on the combination of unique and extreme properties of diamond and the variety of film properties obtainable through tuning the microstructure, morphology, impurities, and surfaces. This issue of MRS Bulletin introduces the latest research, recent applications, and the challenges ahead for CVD diamond films.
