Is CVD Diamond Ready to be an Electronic Material ?
The recent downturn in gem-quality synthetic diamond production presents a unique opportunity to redirect sophisticated CVD systems and skilled process engineers toward electronic and quantum applications. While CVD diamond has long promised revolutionary capabilities for electronics and quantum computing, widespread adoption remains constrained by the limited availability of large-area, high-quality substrates at commercial scale.Significant advances in materials engineering have emerged through novel approaches to diamond synthesis and modification. The incorporation of deuterium during growth has revealed fascinating insights into isotope effects on diamond's electronic properties, while innovative diamond foil/membrane technology has enabled unprecedented control over strain engineering and doping profiles. These developments have been complemented by breakthroughs in surface termination and interface engineering, crucial for electronic device integration.The field now stands at a critical turn point where fundamental research into growth mechanisms, defect formation, and carrier transport can benefit from sophisticated synthesis capabilities. Key research priorities include understanding the role of plasma chemistry in controlling impurity incorporation, elucidating mechanisms of extended defect formation during heteroepitaxial growth, and developing novel approaches to selective doping and defect engineering. These fundamental investigations are essential for realizing diamond's potential in quantum and electronic applications, where precise control over material properties at the atomic scale is paramount.
