This lab is the first one to develop researches on materials modification by ion implantation in China. Its advantages in ion species, range of implanted energy, beam intensity, materials modification mechanism have been well known by experts at home and abroad. The MEVVA ion source project and its application in materials modification have gained great achievements in this lab under the support of continued 4 national 863 high-tech projects. The MEVVA ion source has won the certificate of national new product, and its series products has been sold to over 30 universities, institutes and factories at home and abroad. The research in this field has won one first class award of national nature science, 8 awards of Beijing science and technology progress and 7 patents. Besides, 7 monographs in this field have been finished in this lab.
The X-Ray Optics Laboratory has developed different types of X-ray lenses, such as parallel beam lens, slightly focusing lens, focusing lens and half focusing lens. The X-ray power density can be increased three orders of magnitude and the minimum detection limit of 10-13 g can be reached in the XRF analysis by using the focusing X-ray lens. The intensity of diffracted x-ray could be increased more than 100 times, when the parallel beam lens or slightly focusing lens is used in the XRD analysis. The research ability for the condensed matter analysis is enhanced greatly by means of the research and development of the x-ray lens. “The monolithic polycapillary x-ray lens and its application” was awarded the first Prize of Progress of Science & Technology by the Education Ministry in 1997 and the National Second Prize of Progress of Science & Technology in1998 respectively. The monolithic polycapillary x-ray lens has been granted the National Certification of the New Product and seven patents, including in China, Germany, Netherlands and United Stats. The x-ray lens has been sold all over the world, specially ordered by some international famous companies, universities and institutes in Germany, Netherlands, United Stats and Japan.
There is a technical line for testing new devices, which occupies more than 500 square meters in this lab. Many tasks were taken on from Ministry of Electronics, Commission of Science Technology and Industry for National Defense, the State 863 Plan projects, projects of National Science Foundation of China and Natural Science Foundation of Beijing Municipal Government. Several semiconductor devices with new structure have been made, 7 Science and Technology Progress Prizes from Ministry of Education and Beijing Municipal Government have been awarded, and 5 national invention patents have been declared or granted. At present, Professor Huang Chang’s idea about Complementary Dual Carrier Field Effect Transistor Integrate Circuit (CDCFETIC) has been testing. Compare with the circuit made of common FET, Professor Huang Chang’s circuit can work in higher frequency with lower power consuming. This maybe brings on breakthrough in technology of microelectronics. In addition, pushing industrialization of SOI material is one of the works in this lab.
Microarc oxidation is a novel surface technology of forming ceramic coatings on Al, Mg, Ti and their alloys. It has been investigated since 1992, funded by the National High-tech program and the National Natural Science Foundation of China. The microarc oxidation coatings on Al, Mg, Ti and their alloys components exhibit higher hardness, excellent wear resistance and corrosion resistance. It will be widely applied in many fields such as military,textile machine,chemical engineering, automobile, electronics, aerospace, aeronautics and medical apparatus.
