In a schematic of a robust, long-duration TERS imaging technique, a metallic nanotip images several points in a large area of a WS2 monolayer placed on a gold thin film (a). A superposition of two different intensity images, pure WS2 at 422 cm-1 and defect scattering of WS2 at 410 cm-1, reveals a high density of nanoscale protrusions in a large-area far-field confocal Raman image (b). A histogram of the same modes shows a defect density of 5.2% in the WS2 sample (c).
