Theoretical calculations predict the formation of phonon vortices at heavy impurities in two-dimensional materials. The vortex morphology depends on the impurity mass and the local symmetry of the defect.
Significance A family of strong yet removable 1- to 2-nm-thick ultrathin monolayer is developed as a corrosion inhibitor for 2-dimensional materials that significantly prolong lifetime while protecting optoelectronic properties in both ambient and harsh chemical or thermal environments. This method is low in toxicity and can be applied to arbitrary substrate with no size limit.
