Materials whose elasticity can be tuned have the poteial to lead to highly flexible chips.
Researchers at the University of Massachusetts Plasma and Fusion Science Ceer (PSFC) led by Hangu Chui and colleagues have recely made a new breakthrough in the well-known quaum magnet technology.
While at first glance it seems that this task is not so complicated, this research has led to the recognition of new applications of materials. Magnets (as well as the concept of electromagnetism itself) are the basis and foundation of all computing devices, and for this reason, advances in the basis of magnetic materials promise to have a profound effect on the developme and corol of these fundameal forces.
By using quaum effects, researchers were able to corol Hall Effect and Berry curvature, both of which are obstacles in basic physics, in a way that is usable and useful for us. The new article of this research team has been published in the highly respected journal Nature and has led to our understanding of the use of chromium telluride for the beneficial use of the two effects meioned to increase productivity and efficiency. To answer the question in which areas this developme is effective, it can be said in any area where magnets are importa, such as: computing, electronics and robotics areas.
The Hall effect refers to a discovery made by 23-year-old Edwin Hall in 1879. Hall found that placing a magnet at right angles to a vertical metal strip with a curre flowing through it deflected the curre to the opposite side of the metal sheet. (Remember that electric curre is the regular moveme of free electrons.)
This asymmetric difference in electric curre became known as the Hall effect. But with the help of quaum mechanics, we can take advaage of this asymmetric behavior. If we consider quaum mechanics in such a way that it opens a way for us to look at this effect at the level of particle physics, it allows us to understand the existing conditions and then influence it.
At this mome, the application of the quaum concept of the Berry bend comes in: in quaum physics, this effect is used for the natural deflection of electric curre (almost what the Hall effect does), with the difference that it is called the unusual Hall effect since it does not require a magnetic field. It turns out that this effect can be used to corol the electric curre much more optimally.
The result of this research has led to a material that exhibits the unusual Hall effect even when compressed and promises great poteial for use in the field of flexible electronics.
