Engineers show nanotube circuits can be made en masse

Stanford electrical engineers have developed a method for making integrated circuit chips with the needed variety of logic gates on the scale and with the parallelism that the semiconductor industry must employ to make chips that are economical.

The Stanford-devised process involves growing nanotubes on a quartz wafer and then transferring them onto a silicon wafer patterned with metal electrodes. The nanotubes could then connect the electrodes to make transistors and logic gates.
