报告摘要：

Graphene is a wonder material with extraordinary properties such as ultra-high mechanical strength, ballistic conductivity, superior thermal conduction, corrosion resistance, making it an ideal material for many applications in nano electronics, display, energy storage, environmental technologies, and augmented armour.

In this talk, I will highlight some of the work our group has done in understanding and manipulating the properties of graphene. Our group pioneered the technique using Raman microscopy to determine the thickness of graphene layers which has now become the standard method for the study of 2D materials; our study on the graphene edge stability has led the discovery of a new type of material, close-edged graphene which have completely novel properties as well as potential applications in nano-electronics and energy harvesting; the transformation between semiconducting and metallic trilayer graphene opens up probability of building electronic devices in pure 3-layer graphene; by controlling the chirality of the pseudospin states in such graphene will result in its bandgap opening and charge separation, which can be used as the chirality-controlled pseudospin diode, transistor, and the advanced graphene devices for logic electronics. In the last part, I will report on some work we have done on applications of graphene composites on energy storage.
