Graphene is a one-atom thick two-dimensional (2D) material material made of carbon. It was first isolated in 2004 and, since thattime, many other 2D materials have been successfully isolated in the laboratory but graphene continues to be the most widelystudied. The material has exceptional properties such as excellent mechanical, electrical, thermal, and optical properties. The factthat all these properties are found within a single material, along with the possibility to influence these properties through chemicalfunctionalization has stimulated great interest in graphene. Graphene films can be fabricated with custom-designed conductivitiesthat are lower, equal to, or higher than that of a metal. Yet, as with semiconductors, a graphene films conductivity can bechanged with an externally applied voltage along the path of the current flow. Because graphene exhibits some electronicproperties that are similar to metals while others that are more similar to semiconductors, this material presents uniqueopportunities for the discovery of new electronic components. In this project, Queens University and Grafoid Inc. (Kingston,Ontario) will use graphene to investigate advanced concepts for tunable high-frequency antennas for ultra low-power wirelesslinks.

石墨烯是由碳制成的单原子厚的二维（2D）材料。它于2004年首次被分离出来，自那时以来，许多其他2D材料已在实验室中成功分离，但石墨烯仍然是研究最广泛的材料。该材料具有优异的机械、电学、热学和光学性能等特性。所有这些性质都存在于一种材料中，沿着，通过化学功能化来影响这些性质的可能性激发了人们对石墨烯的极大兴趣。石墨烯薄膜可以制造成具有定制设计的电导率，其电导率低于、等于或高于金属的电导率。然而，与半导体一样，石墨烯薄膜的导电性可以随着沿着电流路径的外部施加电压而改变。由于石墨烯表现出一些类似于金属的电子特性，而另一些更类似于半导体，这种材料为发现新的电子元件提供了独特的机会。在这个项目中，皇后大学和Grafoid Inc.（金斯顿，安大略）将使用石墨烯研究用于超低功率无线链路的可调谐高频天线的先进概念。
