Nanotube Circuits Made Practical

Abstract:
Many experts believe that carbon nanotubes could eventually replace silicon in microelectronics because of their potential for superior speed and reduced power consumption. And over the past several years, researchers have made transistors out of carbon nanotubes. However, it's still difficult to make reliable circuits out of them. One problem is that the nanotubes, used for transistors that make up the circuits, tend to be fabricated in different directions, making it impossible to know which nanotube form which transistor. And such a chaotic arrangement can lead to electrical malfunctions. But now researchers at Stanford University have written a program that finds a working circuit layout, no matter how disorganized or misaligned the nanotubes.
