Submission + - Making graphene work for real-world devices->

aarondubrow writes: Graphene, a one-atom-thick form of the carbon material graphite, is strong, light, nearly transparent and an excellent conductor of electricity and heat, but a number of practical challenges must be overcome before it can emerge as a replacement for silicon in electronics or energy devices. One particular challenge concerns the question of how graphene diffuses heat, in the form of phonons. Thermal conductivity is critical in electronics, especially as components shrink to the nanoscale. Using the Stampede supercomputer at the Texas Advanced Computing Center, Professor Li Shi simulated how phonons (heat-carrying vibrations in solids) scatter as a function of the thickness of the graphene layers. He also investigated how graphene interacts with substrate materials and how phonon scattering can be controlled. The results were published in the Proceedings of the National Academy of Sciences, Applied Physical Letters and Energy and Environmental Science.
