carbon semiconductor nanotubes
[26 Apr 2001] The features of conventional microelectronic circuits are getting smaller and smaller - and they will soon
reach the limit imposed by the fundamental properties of silicon. Although physicists are optimistic that carbon nanotubes
could step into the breach, their electronic properties are not well established and the nanotubes are hard to manipulate.
Now two teams in the US have made substantial headway. Charles Lieber's team at Harvard University has uncovered the
electronic behaviour of several types of nanotube. Meanwhile, Phaedon Avouris and colleagues at IBM have devised a technique
to separate metallic and semiconducting nanotubes (Min Ouyang et al 2001 Science 292 702; P G Collins et al 2001 Science 292
706).
