Open AccessIdentifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides
Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent obser...

Open AccessFrustrated supercritical collapse in tunable charge arrays on graphene
The photon-like behavior of electrons in graphene causes unusual confinement properties that depend strongly on the geometry and strength of the surrounding potential. We report bottom-up synthesis of atomical...
