Using magnetite, common magnetic iron oxide, and 190-curing, scientists claim that it will be possible to create microchips in several orders of magnitude from everything we know today
Today chip companies are mainly Intel See the end. The end of the race to faster processors that maintain a sensible energy and heat envelope but provide increasing power. This is because more and more difficult to minimize the transistors used in memory components, Processors And other vegetables without encountering problems related to magnetic fields in the world of single atoms.
Therefore, many researchers are trying to solve the problem from other directions. One of these directions is the use of different materials than the old silicon that has accompanied us for decades. The US Department of Energy has revealed it now New research Which runs in his labs and checks new materials for the continuation of the race.
The problem with the search for new materials so far has been the ability to test the speed at which the conductivity of a given material can be changed from conductor to isolated. This capability is needed to see how quickly a transistor made of this material will work.
|Magnetite in its natural form|
Magnetite electrical circuit breaker speed was measured at one billionth (1 / 1000000000) - thousands of times faster than silicon-built transistors. The problem is that in order to reach this speed, the magnetite must be cooled to 190 degrees below zero to lock the electric chargers in place. Not particularly practical for desktops.
What is really interesting is the process used to make the measurement. So far, it has not been possible to measure the speed of transmission change in potential materials for the replacement of silicon. Because optical lasers are not precise enough for this purpose. However, with strong and short x-ray pulses extending from the quadrillionth of a billionth of a billionth, the researchers were able to observe and measure the moment of change from isolated to conductor.
|The next candidate: Venium dioxide|
In addition, they also noticed that only certain atoms of matter became conductors while other parts of it, in its center, remained isolated. Electrons, however, were still able to pass through these isolated regions, which showed that the transition between insulator and metal does not require that the entire material content becomes a conductor so that it can serve as a transistor.
Researchers are continuing to look for more practical materials that can do the job while at room temperature. One of the promising candidates is called "Vandium Dioxide", which the team is currently testing. If the appropriate material is found to behave similarly to magnetite but at room temperature, the next step would be to find a way to induce the required change (the "conductor-isolator" switch) without the need for a laser - and preferably using short, strong electrical pulses, much like regular transistors.
The increasing difficulty of chip companies in continuing to accelerate the transistor in the coming years and in the foreseeable future could lead to a slowdown in industry on the one hand, and innovation on the other. The innovation will come from the need to improve the software using the existing hardware, since the software is always lagging behind the hardware running forward.
It is possible that in the end it will turn out that the slower pace of the race will turn out to be a blessing rather than a curse. But until then, researchers will continue to look frantically for ways to extend Moore's law as much as possible.
Should we extend Moore's Law, or is it time to look in other directions? Share your thoughts with comments!
