Carbon-based Nanomaterials and Nano-optoelectronics

碳基材料是纳米技术研究的核心。2010年诺贝尔物理学奖授予了单层碳原子石墨烯的发现，这开启了一个更加积极的探索，即将该领域积累的大量基础物理学成果转化为商业应用。我们的研究重点是溶液处理的物理和应用，通过组装石墨烯片来制备大面积石墨烯薄膜，就像拼图一样，覆盖大面积的衬底。这些薄膜被用作低成本组装许多未来设备的平台，包括：柔性塑料太阳能电池，用于水净化和生物传感的过滤装置，以及用于电子应用的热汇。我们的团队使用基于纳米光学的专业工具来优化石墨烯薄膜的特定应用。

Carbon-based materials are at the core of nanotechnology research. The 2010 Nobel Prize for Physics awarded to the discovery of graphene, a single layer of carbon atoms, has opened an even more vigorous quest for translating into commercial applications the tremendous amount of fundamental physics that is being accumulated in this field. Our research is focused on the physics and applications of solution-processed, large-area graphene thin films prepared by assembling graphene platelets like jigsaw puzzles to cover large areas of a substrate. These films are used as platforms for cost-effectively assembling a number of futuristic devices including: flexible plastic solar cells, filtration devices for water purification and biosensing, and thermal sinks for electronic applications. Specialized tools based on nano-optics are used by our group to optimize graphene thin films for specific applications.
