Ultrathin transistors for faster computer chips

For decades, the transistors on our microchips have become smaller, faster and cheaper. Approximately every two years the number of transistors on commercial chips has doubled—this phenomenon became known as "Moore's Law." But for several years now, Moore's law does not hold any more. The miniaturization has reached a natural limit, as completely new problems arise when a length scale of only a few nanometers is approached.
