Scientists have proposed a new technology for manufacturing transistors
If you begin to delve into the circuitry of modern electronic gadgets, you may find that they are all built on the same basic elements - transistors. These electronic devices were invented in the middle of the last century and are now used almost unchanged. Transistors are based on n-p-n and p-n-p junctions, and they all use materials such as germanium, silicon, and gallium arsenide in their design. In general, transistors have led to a dramatic reduction in power consumption and an increase in performance compared to lamps. But now something even more energy efficient is needed.
American researchers from two major research centers, the University of Buffalo and the University of Nebraska, proposed a radically new technology for making transistors. Its peculiarity is that it involves a departure from already established principles. Keke He and Jonathan P. Byrd's magnetoelectric transistors could usher in a new direction in electronics. These devices are based on graphene. Its layer is only a few atoms thick and is placed on a chromium oxide substrate. This produces a transition whose resistance can be controlled flexibly. In addition, the polarity of the transition can be switched as needed.
The use of such magnetoelectric controlled transistors will significantly reduce power consumption. Furthermore, the size of chips can be significantly reduced by allowing the same polarity transitions to be used to create different circuits within one circuit. The authors of the technology have information that allows reducing the number of transistors in circuits by 75%. If the technology begins to develop, we should expect its use in digital electronics. In particular, chips with magnetoelectric transistors can be used in gadgets.
