New invention of Lawrence Berkeley Team-Smallest Transistor (1nm)

A research team of Lawrence Berkeley Laboratory developed a smallest working transistor of 1nm gate, under the guidance of faculty scientist Ali Javey at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).

“We made the smallest transistor reported to date,” said Javey, lead principal investigator of the Electronic Materials program in Berkeley Lab’s Materials Science Division. “The gate length is considered a defining dimension of the transistor. We demonstrated a 1-nanometer-gate transistor, showing that with the choice of proper materials, there is a lot more room to shrink our electronics.”
