Research Progress on Synthesis of Large-scale Single Crystal Diamond by MPCVD

Owing to many excellent properties that cannot be replaced by polycrystalline diamond, single crystal diamond is one of the most important materials in the high-tech fields in the 21st century. With the continuous improvement of synthetic technology, great progresses have been achieved on growth rate, quality and size of single crystal diamond synthesized by MPCVD. At present, using the latest MPCVD technology to synthesis single crystal diamond, researchers can get a grow rate of 200 μm/h and a size of 1 inch, which support the applications of single crystal diamond on high-tech fields such as ultra-precision machining, optical components, semiconductors, detectors, etc. In this paper the progress of single crystal diamond synthesized by MPCVD in the new century is reviewed and its applications are briefly introduced.
