You may have heard all the attractions of graphene this material, such as excellent strength, excellent electrical properties, thermal conductivity and electron mobility. These different features make graphene in the touch screen, semiconductor, solar cells, supercapacitors and other fields have a huge impact.
However, only in the case of pure raw materials, can produce high-performance graphene. The production of high performance graphene is very challenging, but the U.S. Department of energy's Argonne National Laboratory found a possible solution to material -- Ultrananocrystalline diamond.
Anirudha Sumant is the leading materials scientists at Argonne National Laboratory, they are currently in cooperation with the University of California at Riverside, the use of ultra nanocrystalline diamond (UNCD) synthesized as graphene substrate. This synthesis ensures the removal of most of the impurities.
The first author Diana Berman (Diana Berman) said: "when I first saw through the scanning electron microscope, found that graphene in this way made a pretty complete, this makes me very shocked. I've been making graphene in different ways, but I've never seen such a good shape."
This way can be synthesized at a lower temperature than the synthesis of graphene, graphene with silicon carbide synthesis way (now widely used way to save more time). The three or four layer of silicon carbide crystal prices close to 1200 U.S. dollars, while the cost of UNCD is less than 500 U.S. dollars, with higher economic benefits.
The Argonne group said, they won a total of three patents. They are now Swedish Institute of space physics and the European space agency cooperation, developed for the Jupiter icy moon detector (JUICE) graphene coating probe plan. The research team is currently developing the Argonne researchers at the University of North Carolina for graphene biosensor probe.
Researchers now report their findings to the "Nature Communications", of course, manufacturing method of laboratory researchers will continue to optimize the graphene.
Previously researchers in Japan improved the production of graphene with silicon carbide, although graphene can obtain higher quality, but there is no way to reduce the cost and.
