American scientists are ready to produce monatomic transistors on an industrial scale

Monatomic transistors are the main building blocks for computers of the future, which will have colossal memory and enormous processing power due to their quantum capabilities. But for implementation it was necessary to put the production of such transistors on stream. This problem was successfully solved by American scientists.

A research group from the National Institute of Standards and Technology, together with the staff of the University of Maryland, proposed a working algorithm for creating a monoatomic transistor.

This research group was the second in history to create such a device, and the first to produce a whole series of single-electron transistors with atomic-scale geometry control.

At the same time, the scientific group demonstrated the possibility of changing the flow rate of individual electrons through the electrical barrier in the transistor. And this is despite the fact that classical physics asserts the impossibility of such control due to insufficient energy.

This effect is purely a quantum phenomenon called quantum tunneling. And its use in microscopic transistors holds great promise.

How a monoatomic transistor works

To obtain a monatomic transistor, the scientific group used an already proven technology, which is as follows:

A layer of hydrogen atoms is superimposed on a silicon chip, which interact with silicon.

Then, using a specialized tunneling microscope, hydrogen atoms are removed from predetermined zones. In this case, the remaining hydrogen layer acts as a barrier for the phosphine gas, and its atoms interact with silicon exclusively in the cleaned areas.

Then, after a series of other manipulations, phosphorus atoms form the basis for stable mono- or low-atomic devices that are quite capable of performing the role of qubits.

At the same time, the described method of superimposing layers of phosphorus atoms is a much more reliable and accurate method, which gives almost 100% result in industrial production.

Now it remains to wait for the prototype of the device assembled on these transistors and we can say that the era of quantum computers has begun!
