Los Angeles | Researchers, including one of Indian-origin, have developed the smallest transistor reported to date, breaking a major size barrier with a gate only one nanometre long.
For more than a decade, engineers have been eyeing to shrink the size of components in integrated circuits.
The laws of physics had set a 5-nanometre threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end 20-nanometre-gate transistors now on the market.
The research team led by Ali Javey from Lawrence Berkeley National Laboratory in the US created the new transistor with a working one-nanometre gate. For comparison, a strand of human hair is about 50,000 nanometres thick.
“We made the smallest transistor reported to date. The gate length is considered a defining dimension of the transistor,” said Javey.
