Two-Dimensional Materials from Materials, Properties to Applications [Presentation]

Abstract

The past few years have seen an explosion of interest in two-dimensional (2D) crystals derived from layered materials that possess strong in-plane bonding and weak van der Waals bonding between crystal planes. Layered 2D materials represent a diverse and largely untapped source of 2D systems with unusual electronic, magnetic and optical properties that are attractive for a wide range of applications from energy storage and catalysis for hydrogen evolution to electronics and optoelectronics. In this talk, the research activities related to 2D materials within the Department of Applied Physics will be reviewed. The bottom-up synthesis of graphene quantum dots will be presented together with their optoelectronic properties. The strain engineering of 2D materials such as graphene, black phosphorus and MoS2 will be discussed. The solution exfoliated BP flakes and quantum dots could enhance the performance of organic solar cells. Furthermore, it can also boost the performance of Li-S batteries significantly.
