Diamond as a semiconductor material with the best insulation and the highest thermal conductivity, but the resistance of the diamond is usually very large, which his application. Japanese researchers braced impurities in diamonds to solve this problem, first made a bipolar transistor, semiconductor components for the development of energy opens a new way.
Japan's Industrial Technology Research Institute recently issued a statement, the diamond semiconductor materials, insulation determined it will not harm the high voltage to ensure good thermal conductivity, it efficiently at high currents due to internal heat divergence.
However, the high resistance of the diamond, as it is a major obstacle to the application. Industrial Technology Research Institute researcher, director Satoshi Yamazaki and other investigators have found that are also the incorporation of impurities into diamond, diamonds also be able to get a good crystal structure.On this basis they developed a high concentration in the mixed impurities in diamond technology and the use of jump conductivity mechanism reduces the resistance of the diamond.
The researchers used a diamond of this low resistance, and eventually developed a high-performance semiconductor components for bipolar transistors required.Bipolar transistors with a current gain, as an efficient power control was widely used in broadcasting, telecommunications, computer, automatic control and household appliance industries.
