Researchers with the Massachusetts Institute of Technology (MIT) have published a new study detailing their discovery of a hybrid particle, one comprised of an electron and phonon combined together in a way that allows them to act as a single particle. Physicists refers to this bond between the two particles as “glue,” explaining that it is 10 times stronger than any previously discovered hybrid of this kind.
Many
people are familiar with the electron, which is a subatomic particle that can
attach to an atom. Fewer have heard of phonons, however, which are called quasiparticles; they’re the result of vibrational energy generated by atoms,
making them neither a particle nor a wave.
The
physicists describe this new hybrid particle as one made from an electron and
phonon potentially “tuned in tandem” with each other (via MIT). The conclusion is
that any stimulation to the electron may also lead to changes in the phonon
“glued” to it. These phonon changes, as a result, trigger changes to a
material’s structure, particularly its magnetic properties.
Why does
this matter? According to the MIT team of researchers, the particle combo paves the way for
tuning both a material’s magnetic and electrical properties. This research has
major implications for the future of electronics, with the physicist explaining that it may be possible to, for example, “tune” the hybrid particles
in certain materials to create “a new kind of magnetic semiconductor.”
Consumers
would benefit from such innovation, as it may usher in gadgets that are more
efficient with improved performance while also shrinking in size. It’s
reasonable to assume a breakthrough like this could also prove useful in
military, aerospace, and other industries — in fact, the study was partially
funded by the US Department of Energy.
One of the study’s co-authors, Batyr Ilyas, explained:
One potential way of harnessing this hybrid particle is, it could allow you to couple to one of the components and indirectly tune the other. That way, you could change the properties of a material, like the magnetic state of the system.
