We have numerically studied microwave plasma discharge for the chemical vapor deposition of single-crystal diamond. It is experimentally confirmed that the arrangement of the seed substrate and local configurations affect the growth rate and macroscopic surface morphology. We found correspondences between experimentally observed growth rates/surface morphology and numerically predicted distributions of microwave power density/substrate temperature/gas flow. These correspondences are instructive information for designing improved reactors that can synthesize larger crystals with a higher quality more efficiently.
