IBM has announced a breakthrough in the implementation of carbon nanotube transistors. The company's scientists have found a solution to the problem that separated the new transistors from mainstream use.
Carbon nanotube transistors could enable the transition to a 10nm process. This is half what the current manufacturing technology can afford. New transistors could revolutionize the creation of computers and completely supplant silicon.
The main difficulty that has so far prevented the use of carbon nanotube transistors is the physical limitation in reducing the size of the contacts of the transistor: with decreasing size, the contact resistance increased.

IBM technology makes this problem a thing of the past with pins that are resistive-independent. The company says their breakthrough will enable the production of miniature contacts down to 1.8 nm or even smaller.
