A special class of materials known as “Weyl semimetals” have unusual physical properties. In these materials, researchers can separate electrons by their “handedness.” That’s whether the electrons’ magnetic moment is in the same direction as the electrons’ movement or the opposite direction.
This results in a host of unique phenomena that researchers can use to turn infrared light into electricity and develop very fast electronic circuits.

Two-dimensional (2D) materials could offer new building blocks for future technologies — but only if scientists can control growth and properties. Strain, caused by “stretching” or “bunching” the atomic structure as a crystal grows, is one way to control these properties.
