Carbon Nanotubes and their Applications
Prof. W.I.Milne, Engineering Department, Cambridge University
13 May 2005, 2:30pm LR6, CUED
Over the past several years Carbon Nanotubes (CNTs) have been touted as
being one of the most promising material systems for future electronic
applications. CNTs are a unique form of carbon filament/fibre in which
sheets of sp2 bonded graphite with no surface broken bonds roll up to form
tubes. Single wall CNTs can exhibit either metallic-like or
semiconductor-like properties and multi-wall tubes exhibit metallic-like
behaviour. Their future application in the electronics industry is based
upon several unique properties which the CNTs possess, e.g. they have the
highest thermal conductivity, they can exhibit ballistic electron
transport and do not suffer from electron migration. However there are
still major problems to be overcome before CNTs can be used in devices and
circuits.
This presentation will cover the growth, characterisation and potential
electronic applications of both SWCNTs and MWCNTs and will attempt to
provide a realistic appraisal of their future in the electronic industry.
