Invented a way to speed up computers many times

American physicists have created the first “magnetic” graphene transistors that can work thousands of times faster than silicon precursors with a hundred times less energy.

Scientists from the U.S. proposed the use of graphene for the production of “magnetic” transistors, where the movement of electrons is controlled by magnetic and not electric fields. Such transistors will work due to the unusual properties of the material: if you add a magnetic field electricity is passed through it faster.

Your graphene transistor, the researchers created without using the graphene. It is a set of 3 nanotubes out of carbon, one of which has a partial “break” in the middle, so it was the equivalent of a narrow strip of graphene. While maintaining constant tension in the two nanotubes controlling the current in this transistor can flow in one direction, and its strength depends on how much current passes through the lateral threads. When changing the current in each tube separately, this device is able to perform certain logic functions that will reduce the complexity of the circuits.

The disadvantage of this “magnetic” transistor is that while he can function at very low temperature – no higher than 70 degrees Kelvin (-203 degrees Celsius). According to physics, this problem is solved, because there are ways to get graphene to work at room temperature.
