Graphene, Nanotubes & Nanowires

graphene nanotubes nanowires

Sunday May 12, 2013, 9:00 am - 5:00 pm, Washington, DC

Technology Focus

The  rapid progress in growing graphene as well as advances in the growth and separation of carbon nanotubes open a wide range of applications. The unique properties of the three folded flat carbon world and the discovery of how to mass produce graphene and nanotubes, gives much hope to replace many often toxic or rare elements in today’s technology products with light weight, energy saving carbon nanostructures.  In addition, there is tremendous progress in growing a variety of inorganic materials in a one-dimensional nanowire form for applications from electronics to sensors.  This course focuses on all the essential aspects in these rapidly growing fields.

Objective

This course will first introduce graphene and carbon nanotubes and related carbon nanostructures, their basic properties and characteristics. The course will give a historic overview and show how carbon nanotubes gained interest and how graphene has suddenly become a hot research field. The fundamental properties will be presented and explained why 3-folded carbon nanostructures have such unusual properties. The most relevant synthesis and processing techniques will be presented. A number of potential applications will be discussed and a review will be given to where nanotubes are already used or will be used in the near future. Safety and health issues will also be discussed.

The course will then cover growth, characterization and applications of various nanowires including Si, Ge, III-V, II-VI, oxides, nitrides and others. Fundamentally, the same materials in the thin film form have been responsible for the revolutions we have witnessed in the last 20 years in the areas of microelectronics, photonics, MEMS etc. Now the expectation is that in the 1-d nanowire form, applications can be extended due to interesting quantum confinement and flawless surface properties.
