Recent advances in atomically thin two dimensional (2D) materials have led to a variety of promising future technologies for post-CMOS nanoelectronics, energy, photonics and opto-electronics. The 2D materials exhibit strong in-plane bonding along with weak out-of-plane bonding, enabling the exfoliation of the materials into single crystal two-dimensional flakes with atomic level thickness. An atomically thin 2D material is defined as a material whose free charges are immobile in one spatial dimension, but mobile in the other two. This property enables 2D materials to have new or superior functions, distinct from traditional bulk materials or thin films. However, challenges in developing such materials into defect-free and large scale in a desired substrate have to be overcome in order to obtain such structures in controllable ways.
This symposium will review recent progress in understanding the atomic scale growth mechanisms and structural control of various 2D nanostructures, developing new growth techniques, revealing novel properties, exploring new chemistry of 2D structures, functionalization engineering in low dimensions and their applications. In addition, this symposium will bring researchers from different disciplines to present their recent advancements in application areas such as electronics, opto-electronics, sensors, composites and energy.
