A team of researchers have found that when the number of electrons on a bilayer graphene (BLG) sheet is close to zero, the material becomes insulating (resists flow of electrical current). This finding suggests that multi-layer graphene might be suitable as an electronic material in the semiconductor and electronics industries. Their research was published recently in Nature Nanotechnology. The research was supported by grants from the National Science Foundation, Office of Naval Research, FENA Focus Center, and other agencies.
A team of researchers at the Bourns College of Engineering at the University of California, Riverside has made a breakthrough in zinc oxide nanowire waveguide lasers. Zinc oxide nanowire lasers could be used to read and process much denser data on storage media. With zinc oxide, a DVD could store four to six hours of music instead of two hours. The research findings have been published in the July issue of Nature Nanotechnology.
