Molecular Self-Assembly in a Poorly Screened Environment: F4TCNQ on Graphene/BN

Scientific Achievement

Using the Molecular Foundry, researchers show that charged molecules that would normally repel one another have been observed to attract each other on graphene due to a novel self-assembly mechanism

Significance and Impact

A new self-assembly mechanism should apply to other charged molecular systems involving 2D materials and provides a new route to engineer useful nanostructures
