The team of Khondaker and Stokes devised a new technique to engineer quantum transistors which will be published in Applied Physics Letters (Issue 92). Computer electronics experts worries about what is going to occur when transistors shrink so small that electron quantum effects begin to play a role. In response, Khondaker and Stokes have controllably fabricated single electron transistors, a device that exploits quantum tunneling and the movement of individual electrons, from individual single-walled carbon nanotubes. Making these devices as small as possible is a key ingredient for effective device operation with the possibility of operating at room temperatures. This technique lays the foundation of large scale fabrication of single electron transistors in computer chips of the future.
