Sentences with phrase «new superlattices»

The new superlattices — called monolayer atomic crystal molecular superlattices — feature a molecular layer that becomes the second «sheet» that is held in place by van der Waals forces — weak electrostatic forces that keep otherwise neutral molecules attached to each other.

However, the new superlattices can have radically different structures, properties and functions.
