Graphene (a single atomic layer of graphite) first experimentally isolated and identified only four years ago, is rapidly revealing its great potential as an important material for future electronic devices. In order to progress towards realistic device applications of graphene, it is important to address the issues which will affect the operation of graphene in real circuits, where high currents will lead to overheating and non-equilibrium charge carrier distributions. The proposed joint project will launch an internationally leading programme involving three research groups which are already well established in graphene research and have expertise in complimentary areas. By combining fabrication technology of graphene-based devices, transport and optical studies, and theoretical modelling, we will investigate the kinetic properties of charge carriers and phonons (lattice vibrations) in graphene over a broad range of operating voltages, temperatures and optical intensities, with the aim to establish and improve the operating characteristics of graphene-based electronic and optoelectronic devices.

石墨烯（石墨的单原子层）仅在四年前首次通过实验分离和鉴定，目前正在迅速揭示其作为未来电子设备重要材料的巨大潜力。为了推进石墨烯的实际器件应用，重要的是解决影响石墨烯在实际电路中运行的问题，其中高电流会导致过热和不平衡电荷载流子分布。拟议的联合项目将启动一个国际领先的项目，涉及三个研究小组，这三个研究小组在石墨烯研究方面已经很成熟，并且在互补领域拥有专业知识。通过结合石墨烯器件的制造技术、传输和光学研究以及理论建模，我们将研究石墨烯中载流子和声子（晶格振动）在广泛的工作电压、温度和光强度范围内的动力学特性，旨在建立和改善石墨烯基电子和光电器件的工作特性。
