The Japan Industrial Technology Research Institute uses microwave plasma CVD (Chemical Vapor Deposition) method to make a crack-free single crystal diamond with a volume of 1 cubic centimeter for the first time. This time, the use of gas that easily expands the synthetic area as a raw material to produce the world's largest high-quality crystal is an important step toward achieving large-scale wafers.

Power semiconductors are widely used in various products and equipment such as electric power infrastructure, automobiles, railway vehicles, industrial equipment, and home appliances. They are important devices to support these products and equipment to achieve high performance and energy saving. The results will not only be applied to electronic fields such as power semiconductors, but also expected to be applied to the field of spintronics. Diamond can process quantum information with high spatial resolution at room temperature and pressure, so it is expected to further improve the performance of sensors and quantum computing devices.
