‘Atomic Dance’ Sheds Light Into The Performance Of 2D materials

A team of materials scientists from Northwestern University have developed a new method to observe the dynamic motion of atoms in atomically thin 2D materials such as graphene and borophene. The thin nature of 2D materials makes them highly sensitive to external environments and affect their stability and reliability in electronic devices. Using a high-resolution, atomic-scale imaging method called electron microscopy, researchers passed electric current to the molybdenum disulfide and witnessed the dynamic motion of sulfur atoms, a phenomenon they termed as “atomic dance”. This eventually causes the failure in the material. Researchers believe the new approach could be used to develop more stable and reliable materials for future wearables and flexible electronic devices.
