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（石墨的单个原子层）首先是在四年前进行实验分离和鉴定的，它迅速揭示了其作为未来电子设备的重要材料的巨大潜力。为了朝石墨烯的现实设备应用迈进，要解决将影响石墨烯在实际电路中运行的问题，在这些问题中，高电流将导致过热和非平衡荷载载流子分布。拟议的联合项目将启动一项国际领先的计划，涉及三个研究小组，这些研究小组已经在石墨烯研究中建立了很好的建立，并且在免费领域具有专业知识。通过结合基于石墨烯的设备，传输和光学研究以及理论建模的制造技术，我们将在广泛的操作电压，温度和光学强度范围内调查石墨烯中电荷载体和声子（晶格振动）的动力学特性，以建立和改善基于石墨烯的电子和光学磁铁的操作特征。
