Interplays of structure and electronics in mesoscopic systems

对纳米尺寸和介观系统的广泛兴趣的一部分是由它们在纳米尺度下联合收割机和混合材料的机械和电子性质的能力激发的。我们研究的长期目标是在基础层面上理解，并利用应用程序，（i）结构和电子自由度的相互作用，以及（ii）相关的电子相，在纳米和介观系统。我们努力探索纳米级力学和电子学将包括石墨烯，金属和半导体纳米晶体，碳纳米管和有机-无机自组装材料等系统。我们将利用专门的实验方法，如门控机械断裂和先进的扫描探针，可以同时探测纳米系统的结构和电子学。首先，我们将研究机械应变石墨烯（石墨单层）晶体管和石墨烯/绝缘体/石墨烯（GIG）双层中的电子输运。将在这些石墨烯系统中探索广泛的物理和应用：

Part of the widespread interest in nanometer-sized and mesoscopic systems is motivated by their capability to combine and hybridize mechanical and electronic properties of materials at the nanoscale. The long term goals of our research are to understand at a fundamental level, and harness into applications, (i) the interplays of structure and electronic degrees of freedom, and (ii) correlated electronic phases, in nano and mesoscopic systems. Our efforts to explore nanoscale mechanics and electronics will include systems such as graphene, metallic and semiconducting nanocrystals, carbon nanotubes, and organic-inorganic self-assembled materials. We will make use of specialized experimental methods, such as gated-mechanical breakjunctions and advanced scanning probes, which can simultaneously probe the structure and electronics of nanosystems. Initially, we will study electronic transport in mechanically strained graphene (graphite monolayer) transistors, and graphene/insulator/graphene (GIG) bilayers. A broad range of physics and applications will be explored in these graphene systems:
