A scientist of Indian origin unveils a new device to send electrons by vacuum

It sends electrons through weak air slots instead of sending them through silicon, said senior author Shruti Nirantar of the Royal Melbourne Institute of Technology, quoted by the Xinhua News Agency.

By revolutionizing transistor technology by sending electrons across the void, a team led by an Australian-born Indian scientist has unveiled a device that eliminates the use of semiconductors, which makes it faster and less subject to warming up.

It sends electrons through weak air slots instead of sending them through silicon, said senior author Shruti Nirantar of the Royal Melbourne Institute of Technology, quoted by the Xinhua News Agency.

"Every computer and every phone has millions or even billions of silicon electronic transistors, but this technology reaches its physical limits where silicon atoms hinder the flow of current, limiting speed and generating heat," he said. Nirantar.

"Our air channel transistor technology has the current flowing through the air, so there is no collision to slow it down or resistance in the material to produce heat," she added. .

Associate Professor Sharath Sriram explained that passing electrons through a solid, atom-charged transistor is like walking on a busy street.

"The crowd slows your progress and drains your energy. On the other hand, traveling in a vacuum is like an empty highway where you can drive faster with greater energy efficiency, "said Sharath.

For decades, the power of computers has grown exponentially, doubling about every two years, according to a process called Moore's Law. However, this growth has slowed, with engineers struggling to further reduce the size of already microscopic transistor components.

The lead author, Nirantar, stated that their method, which involves passing electrons through air slots 50,000 times smaller than the width of a human hair, takes a different path from the miniaturization of a human. transistor to enforce Moore's law for many more decades.

The device at the nanoscale is designed to be compatible with the manufacturing and development processes of modern industry, while offering applications for future use in the space, including in the nano satellites.
