Los Angeles, Oct 7 (PTI) 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. 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. "We made the smallest transistor reported to date. The gate length is considered a defining dimension of the transistor," said Javey. These properties, in addition to mass of the electron, help improve the control of the flow of current inside the transistor when the gate length is reduced to one nanometre.
