 · A new kind of computer chip (array of chips on the wafer pictured above) contains thousands of transistors made from carbon nanotubes, not silicon. The prototypes can't yet compete with silicon chips for size or speed. But carbonnanotubebased computing promises to usher in a new era of electronics that are faster and more energy efficient.

Graphite ( C ) is a true conductor like a metal ( not a semiconductor like ore minerals), and it is very conductive, even in very low concentrations. It is also chargeable (a different physical property see the separate chapter on Chargeability), and it is notoriously difficult to distinguish from metallic ore minerals.

Limestone batteries could be the key to transporting energy across huge distances, according to chemists in Germany. The idea, which would be used to take solar energy harnessed in the African desert to cities in Europe, might be more efficient than power lines, and could even sequester carbon dioxide emitted by fossil fuel plants.

A first insulating film with a dielectric constant lower than that of a silicon oxide film is formed on a semiconductor substrate. Next, a metal film or a second insulating film, which has degrees of moisture absorption and deformation in an oxygen plasma process and exposure to a resist releasing solution equal to or less than those of a silicon oxide film, is formed on the first insulating film.
