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:

人们对纳米尺度和介观体系的广泛兴趣的部分原因是它们能够在纳米尺度上结合和杂交材料的机械和电子性能。我们研究的长期目标是在基础水平上了解纳米和介观系统中结构和电子自由度的相互作用，以及(Ii)相关的电子相，并将其应用于应用。我们探索纳米力学和电子学的努力将包括石墨烯、金属和半导体纳米晶、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，如门式机械断路器和先进的扫描探针，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(石墨单分子层)晶体管和石墨烯/绝缘体/石墨烯(GIG)双层膜中的电子传输。将在这些石墨烯系统中探索广泛的物理和应用：
