Stanford scientists build first carbon nanotube computer

By - September 26, 2013 3 Pictures
In a technological tour de force, researchers at Stanford University have constructed a one-bit, one-instruction programmable computer on a chip using carbon nanotube-based electronics for all logic elements. Containing 178 carbon nanotube field-effect transistors, the computer is only able to carry out only one instruction, called SUBNEG. However, SUBNEG is Turing-complete, allowing the computer to run, albeit with an extraordinary level of inefficiency, any program, given enough memory, time, and programming ingenuity. Read More
