Abstract

For the past 10 years, diamond, and more particularly single crystal diamond, has attracted a strong interest from the scientific community, mostly fueled by the significant progresses achieved in the synthesis of high purity and crystalline quality material and the reduction of its production cost. Thus new devices and new areas of application are emerging, especially in the field of electronics device and quantum sensing that are currently booming. This presentation will outline the steps that enabled spectacular progresses in diamond growth, in particular in obtaining thicker and larger single diamond crystals. We will then address the developments that have been made to try to reduce the production costs of the material which remain a major impediment to its development. Finally, even if significant growth rates have been achieved, it is also essential to control the crystal quality and more particularly dislocations. The latest development done in this area will be presented.
