France's highly conductive diamond semiconductor

The French National Scientific Research Center for solid state physics and crystallization laboratory scientists have developed a high performance than ordinary diamond semiconductor and a new type of diamond semiconductor nearly 10 thousand times, provides the development of new materials for electronic components.

Diamond is made up of carbon atoms, which is not conductive. However, if a small amount of boron or nitrogen is added into the diamond, it will become a semiconductor. Because of its small size and high temperature resistance, it has a unique advantage in the manufacture of electronic or optoelectronic components. However, it is difficult to fabricate diamond semiconductor with higher conductivity, so the further development of microelectronic device manufacturing technology has encountered a bottleneck.

According to the British "nature" magazine in the latest issue of "material" magazine reported that the French National Scientific Research Center for solid state physics and crystallization laboratory scientists believe that the conductivity of diamond semiconductor of the traditional manufacturing technology is not ideal, should try to add new elements to the diamond semiconductor, change the carbon structure of the material, in order to improve the conductivity diamond semiconductor. According to this idea, the researchers of P diamond semiconductor elements added hydrogen containing boron, found by research materials into a N type diamond semiconductor, its conductivity than in the past the traditional method of diamond semiconductor manufacturing is nearly 10 thousand times higher.

The chip made of diamond semiconductor film can work normally at several hundred degrees Celsius, and the working temperature of the silicon chip should not exceed 150 degrees celsius. In addition, the volume of diamond electronic components can be smaller, it can be used in the field of silicon electronic products can not be used to play an irreplaceable role. Evaluation of the material, said that the French scientists will have a direct impact on the field of microelectronics, and provide a new foundation for the research and application of semiconductors.
