Chances are, the chips in the electronic device you're using to read this right now are based on silicon. As demand grows for faster, better, smaller electronics device, the question arises — what comes after silicon? Researcher John Rogers talks about the possibilities of electronics based on carbon nanotubes.
Rogers and colleagues, writing in the Proceedings of the National Academy of Sciences, describe creating a six-transistor radio capable of tuning in to regular FM radio transmissions. The active components of the device, all nanotube-based, would fit on the head of a pin.
