True to Mooreâs Law, the number of transistors on a microchip has doubled every year since the 1960s. But this trajectory is predicted to soon plateau because silicon â the backbone of modern transistors â loses its electrical properties once devices made from this material dip below a certain size.

In these materials, researchers can separate electrons by their âhandedness.â Thatâs whether the electronsâ magnetic moment is in the same direction as the electronsâ 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.
