Berkeley Lab research team builds world’s smallest transistor

A team of researchers at Lawrence Berkeley National Laboratory has successfully built a 1 nanometer (1nm) long transistor, which is said to be the world's smallest functional transistor ever made.

To build the 1nm-long transistor, the Berkeley Lab research team used carbon nanotubes and molybdenum disulfide, which is also known as MoS2.

The size of transistor has always been an important part of advancing computer technology. The smaller the size of a transistor, the more one can fit on a chip, creating a faster and more efficient processor.

Current generation computer technology is using 14nm scale transistors. Intel is expected to bring 10nm semiconductors sometime in 2017 or 2018 with anticipated products like Cannonlake line.

Thus, the successful development of 1nm-long transistor by the Berkeley Lab research team has beaten Intel's that aim to the punch.

In the 1nm-long transistor, the MoS2 acts as the semiconductor and the hollow carbon nanotube functions as the gate to manage the flow of electrons.
