Few layer two dimensional materials, Graphene & Nanowires: Fundamentals, Advances & Manufacturing

graphene nanotubes nanowires

Sunday, May 22, 2016, 9:00 am - 5:00 pm, Gaylord National Convention Center, Washington, DC

Technology Focus

Progress in the synthesis of highly crystalline few layer two dimensional materials, nanotubes and nanowires with exceptional and unique properties compared to their bulk counterparts opens up a wide range of applications. The last two decades brought enormous progress in understanding low dimensional nanomaterials such as nanotubes which triggered off research on nanowires, graphene and few layer two dimensional materials. Fast electronics, transparent electrodes, detectors, sensors, actuators and carbon nanocomposites are some among many potential application areas. This workshop will give an overview, include recent findings and focus on all essential aspects in these growing fields.

Objective

This workshop will first introduce graphene, two dimensional materials and carbon nanotubes and related carbon nanostructures, their basic properties and characteristics. Second the growth, characterization of carbon nanotubes, graphene and various nanowires including Si, Ge, III-V, II-VI, oxides, nitrides will be discussed. The most relevant synthesis and processing techniques will be presented. The fundamental structural, optical and electronic properties will be considered as a function of the characteristic structural properties such as diameter and length or number of layers. Fundamentally, the same materials in thin film form have been responsible for the revolution we have witnessed in the last 20 years in the areas of microelectronics, photonics, MEMS etc. Safety and health issues will also be discussed. The second part of the workshop will review a wide range of applications of carbon nanotubes, nanowires and graphene which are either in use today, under development or are considered for specific applications in the near future.
