Paragraph starter
The synthesis of high-quality single crystal diamond (SCD) via Microwave Plasma Chemical Vapour Deposition (MPCVD) presents a significant opportunity due to its exceptional material properties. However, a critical limitation identified in research up to 2016 was the constrained lateral growth of SCD, typically restricted to 10-15 mm, primarily due to the small dimensions of available seed substrates. This size constraint hinders its application in areas demanding larger surface areas, such as advanced electronics and optics, despite the material's theoretical advantages over polycrystalline diamond, HPHT diamond, and even natural diamond in specific performance metrics.
