This achievement has opened up a new way for the development of new semiconductor materials.
Diamond is the hardest material in the world, but it can't be used for steel cutting at high temperatures because it reacts with iron. Cubic boron nitride is a superhard material that is second only to diamond in hardness. It has good chemical stability at high temperatures and does not react with iron.
If a superior composite of diamond and CBN crystal materials can be combined to develop a new composite material, it is expected to develop a new processing tool for the processing of iron-containing hard rock and hard workpieces. In addition, the bonding of these two semiconductor materials can also be used in the development of new semiconductors. These technologies were previously blank.
Recently, the research team of Tohoku University in Japan published their diamond-CBN bonding research results in the journal Nature Communications. Japan National Institute of Materials Science and Japan Fine Ceramics Research Center used ultra-high resolution scanning electron microscopy to observe the bonding of diamond-CBN crystal materials; and carried out a large number of theoretical calculations.
The researchers found that the diamond-CBN bonding material has a regular shaped pattern structure. Surprisingly, for some lattice defects formed on the boundary layer of the diamond-CBN material, the main structure type can be calculated only when the irregularity of the above pattern is analyzed.
The research team intends to further study the characteristics of diamond-CBN bonding materials in the next step, hoping to master the technology of lattice defects on the crystal layer of diamond-CBN.
