Abstract

     In this talk, I will summarize the recent research on synthesis, characterization and applications of 2D semiconducting nanomaterials in my group [1]. I will introduce the synthesis and characterization of novel 2D semiconducting materials, such as graphene-based composites [2] and single- or few-layer metal dichalcogenides nanosheets [3], especially the first-time synthesized hexagonal-close packed (hcp) Au nanostructures on graphene oxide [4]. Then I will demonstrate the applications of the 2D nanomaterials in chemical and bio-sensors [5], solar cells [6], electric devices [7], memory devices [8], conductive electrodes [5b, 6, 7a, 8a, 9], etc.

Keywords: 2D semiconducting nanomaterial; Graphene; Nanomaterial; Nanodevice; Field-effect transistor; Sensor; Clean energy
