- 10 July 2009
This work used carbon isotope labeling in conjunction with Raman spectroscopic mapping to track carbon during the growth process and shows that at high temperatures sequentially introduced isotopic carbon diffuses into the Ni first, mixes, and then segregates and precipitates at the surface of Ni forming graphene and/or graphite.
Two-Dimensional Phonon Transport in Supported Graphene
It is shown experimentally that κ of monolayer graphene exfoliated on a silicon dioxide support is still as high as about 600 watts per meter per kelvin near room temperature, exceeding those of metals such as copper.
