IT News looks at the death of the silicon chip as newer materials are needed to improve performance:|
One team of researchers at the Leeds University in the UK have proposed to replace silicon chips with carbon nanotubes, which are electrically-conducive tubes of pure carbon that are tens of times thinner than a human hair.It'll be interesting to see what eventually happens with this. Don't expect silicon to die for everything, though - just the technologies that are pushing the envelope in transistor sizing and speed.
Already, some elements of computer circuits such as transistors have been constructed from individual carbon nanotubes. However, scientists have been as yet unable to precisely arrange nanotubes into circuit patterns, which is necessary to determine how each tube conducts electricity.
