ProcessorResearchers from the universities of Purdue, in the United States, and Melbourne and New South Wales, in Australia, created the smallest transistor has developed throughout the history of computing.

The team used a single atom of phosphorus to the creation of the transistor. It has only 0,1 NM, what represents a significant reduction in size of processors. For comparison purposes, newer Intel processors of transistors have 22 nanometer. According to the Indian Express, a criação é mais uma reinvenção da technology atual do que a criação de uma nova. ”This is a good demonstration of control of matter on the atomic scale to make a real device”, says Michelle Simmons, team leader. She explains that, com a transição para devices em escala atômica, “estamos entrando em um novo paradigma onde a mecânica quântica promete um rompimento da technology current”.

However, há um problema que impede a utilização da nova tecnologia em computers: single Atom transistors superaquecem easily, and need to be kept at temperatures below-196º Celsius, using liquid nitrogen.

Gerhard Klimeck, staff researcher, explains that, at high temperatures, the electron from the atom moves out of the channel should be stopped: “For this Atom act as metal, you have to keep the electrons in this channel. If someone develop a technique to contain the electron, ela poderá ser usada para construir um computer que irá trabalhar em uma temperatura base. This is a crucial issue for this technology”, says.
