Electro optical effects in graphene coated porous silicon

Aeponyx是一家快速发展的加拿大公司，提供颠覆性的电信技术，与RichardArès教授领导的舍布鲁克大学纳米材料团队之间的新合作将探索创新方法，利用一种新型纳米复合材料的特性，将其整合到公司的产品中。石墨烯包覆的多孔半导体是由多种半导体材料通过电化学方法获得的介孔结构。孔壁上覆盖着一层只有几个原子厚的类似石墨烯的层--这一过程从根本上改变了主体半导体的性质，形成了一种复合材料。纳米复合材料的电光特性尚不清楚。该项目旨在测量这些性能，并探索纳米复合材料在电信应用中的应用。目标应用将是将纳米复合材料集成到目前Aeponyx的光学平台制造工艺中，该平台将MEMS与无源氮化硅波导相结合。最终的成功整合将意味着Aeponyx的产品将成为完全单片的，并以大幅降低的成本生产。该项目将使用在USherbrooke开发的纳米复合材料合成和基于荧光素的纳米纤维的专有技术，沿着Aeponyx对器件制造挑战和相关应用的丰富知识。

This new collaboration between Aeponyx, a rapidly growing Canadian company that offers disruptivetelecommunication technology, and the Université de Sherbrooke nanomaterial team, led by Professor RichardArès will explore innovative ways to exploit the properties of a new kind of nano-composite material forintegration within the company's products. Graphene-coated porous semiconductors are made of a variety ofsemiconductors, whose mesoporous structures are obtained by an electrochemical process. The pore walls arecoated with a graphene-like layer of a few atoms thick - a process that radically changes the properties of thehost semiconductor, forming a composite. The electro-optical properties of the nanocomposites remainunknown. This project aims to measure these properties and explore the use of the nanocomposites in thecontext of the telecommunication applications. The target application will be to integrate the nanocompositewithin the current Aeponyx fabrication process for their optics platform that combines MEMS with passivesilicon nitride waveguides. An eventual successful integration would mean that Aeponyx's product wouldbecome fully monolithic and be produced at radically reduced cost.The project will use the know-how developed at USherbrooke for both the nanocomposite synthesis and forsemiconductor-based nanofabrication, along with Aeponyx's strong knowledge of the device fabricationchallenges and related application.
