Nanotube single-electron transistor is ideal for molecular computers

The first single-electron transistor (SET) to operate at room temperature have been developed. Its minute size and low-energy requirements should make it an ideal device for molecular computers, as reported in the 29 June issue of Science.

SETs only require one electron to toggle between on and off states. In contrast, transistors in conventional microelectronics use millions and are limited in packing density because of excessive heat.
