Chips Could Crunch at Light Speed

Researchers at IBM have used carbon molecules to emit light, a breakthrough that could replace silicon as the foundation of chips and lead to faster computers and telecommunication equipment.

The focus of the research team was ultratiny, tube-shaped carbon molecules, or nanotubes, that are more than 50,000 times thinner than an average human hair, according to a statement from IBM released this week.

The scientists were able to engineer the carbon nanotubes not only to conduct current, but also to emit light.
