Symposium O: Beyond Graphene—2D Atomic Layers from Layered Materials

Spring 2013 Logo

Beyond Graphene—2D Atomic Layers from Layered Materials

The discovery of graphene, made of a single atomic layer of carbon, can be considered as a defining point in the research and development of stable, truly 2D material systems. This breakthrough has opened up the possibility of isolating and exploring the fascinating properties of atomic layers of several other layered materials, which upon reduction to single/few atomic layers, will offer functional flexibility, new properties, and novel applications. However, challenges in isolating such materials into free-standing 2D atomic layers have to be overcome in order to obtain such structures in controllable ways.
Thus, the underlying theme of this synthesis is the development of stable atomic layers from 2D material systems via different synthetic approaches, their characterization, and the exploration of their structure-property correlations.

Some of the material systems where preliminary work has already come out are nitrides (e.g., hexagonal boron nitride), dichalcogenides (e.g., molybdenum sulfide) and oxides (e.g., vanadium pentoxide). The approaches in isolating and studying atomic layers of these materials are system specific. There is enormous interest in building devices and functional materials based on such isolated atomic layers of different compositions to complement those from graphene. There is strong evidence that it is important to address the relevant scientific issues in this area through synergistic experimental/theoretical efforts, and the symposium will reflect this approach. Interdisciplinary topics related to the materials science, chemistry, physics, and engineering of non-graphene 2D atomic layers of mainly oxides, nitrides, and sulfides (but not excluding other compositions) will be discussed during the symposium with a long-term outlook on some of the applications of these materials. The symposium will only target the following noncarbon systems consisting of layered materials: 2D sheets, nanoribbons, and tubules. Other nanostructures such as nanorods, nanowires, nanoparticles, etc., will be out of the scope of this symposium.

Session topics will include

  • General properties of 2D-layered oxides, nitrides, and sulfides
  • General properties of flat and tubular 1D-layered systems: nanotubes and nanoribbons
  • Creation of atomic layers from layered materials by exfoliation and unzipping
  • Creation of atomic layers from layered materials by chemical vapor deposition
  • Chemical modification of 2D-layered materials and derivatives.
  • Structural and electronic characterization of 2D-layered materials including sheets, nanoribbons, and concentric tubules
  • New physics of layered systems: sheets, tubules, and nanoribbons
  • Applications of 2D-layered materials and derivatives

A joint session with Symposium P: Graphene and Related Carbon Nanomaterials is being considered.
