Superconducting magnet for magnetotransport studies of mesoscopic systems

我们要求超导磁体系统和氦检漏仪，以支持我们的长期目标，了解纳米/介观系统中的结构和电子自由度的相互作用。支持的研究计划在NSERC-发现“介观系统中结构和电子学的相互作用”中有详细描述。我们将使用这些设备在介观系统，如石墨烯（单层石墨）结构，碳纳米管，金属和半导体自组装材料的磁输运研究。磁体可以实现的大磁场（14特斯拉），以及检漏仪在我们的低温低温恒温器中监测真空的能力，对于研究介观系统中的大量相关电子态是必要的，例如量子霍尔效应，局域化效应和近藤效应。在这里，我们简要地讨论了两套短期目标，这些设备将被使用：应变石墨烯和石墨烯/绝缘体/石墨烯双层的量子霍尔态的研究。

We request a superconducting magnet system and a helium leak detector to support our long term objectives of understanding the interplays of structure and electronic degrees of freedom in nano/mesoscopic systems. The research program to be supported is described in details in the NSERC-Discovery "Interplays of structure and electronics in mesoscopic systems". We will use these equipments in magnetotransport studies of mesoscopic sytems such as graphene (monolayer of graphite) structures, carbon nanotubes, and metallic and semiconducting self-assembled materials. The large magnetic field that the magnet can achieve (14 Tesla), and the leak detector's capability to monitor the vacuum in our low-temperature cryostat are necessary to study a large number of correlated electronic states in mesoscopic systems, such as the quantum Hall effects, localization effects and the Kondo effect. Here, we briefly discuss two sets of short term objectives where these equipments will be used: studies of the quantum Hall states in strained graphene and in graphene/insulator/graphene bilayers.
