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.

石墨烯是一种由碳制成的一维二维（2D）材料。它于2004年首次隔离，自那时以来，许多其他2D材料已成功地在实验室中分离出来，但石墨烯仍然是最广泛研究的。该材料具有出色的特性，例如优秀的机械，电气，热和光学特性。所有这些特性都在单个材料中发现，以及通过化学功能化影响这些特性的可能性激发了对石墨烯的极大兴趣。石墨烯膜可以用定制设计的电量iesthat制造，较低，等于或高于金属。然而，与半导体一样，石墨烯膜的电导率可以用沿当前流动路径的外部施加的电压来表达。由于石墨烯表现出一些类似于金属的电子杂质，而其他类似于半导体的电子份量，因此该材料为发现新的电子组件提供了独特的运动。在这个项目中，皇后大学和Grafoid Inc.（安大略省金斯敦）将使用石墨烯研究超低功率无线链接的可调高频天线的高级概念。
