Illustration of a P-N Junction in a Heterostructure

Caption

This is an illustration of a p-n junction in a heterostructure made of pristine and nitrogen-doped ("glowing blue") graphene nanoribbon segments.The steep change in electrostatic potential across the interface region is expected to lead to high charge carrier separation efficiency, as schematically illustrated by oppositely moving electrons (red) and holes (blue).
