The team’s results are the first case of a 3D crystal with that property. The flat band term refers to the electron energy bands. Normally, the electrons change energy levels based on momentum.

Sometimes an extra layer of atoms squeezes between other layers during the crystal's formation; sometimes there are holes where atoms are missing. Later, after the metal has solidified ...

When a metal cools and is transitioning from liquid to solid, its atoms come together to form tiny grains, or crystals. Even though the crystalline structure does not continue from crystal to ...
