Gas raw materials make one single crystal diamond cubic centimeter level

Japan's industrial technology research institute by microwave plasma CVD ( Chemical vapor deposition) Method, using gas system for the first time to volume 1 no crack of single crystal diamond cubic centimeter level. The area of gas as raw material, the easy to expand synthesis level to produce the world's largest high quality crystal, this outcome is a significant step to achieve large wafer.

power semiconductors are widely used in electric power infrastructure, automobile, railway vehicle, industrial equipment and household appliances and other products and equipment, is to support the product and equipment of high-performance and saving energy device. The results not only can be applied to electronic field, such as the power semiconductors, is expected to also can be applied to spin electronics field. Can the diamond at room temperature and pressure processing of high spatial resolution of quantum information, etc. , therefore is expected to improve the performance of sensor and quantum computing equipment and so on.
