Nanodot experimental setup

Caption

On the left is an illustration of the experimental setup from this study. Molybdenum diselenide nanodots, represented by red triangles, are embedded in tungsten diselenide and encapsulated by hexagonal boron nitride (hBN) on top and bottom. A focused electron beam, shown in green, in a scanning transmission electron microscope (STEM) is aimed at the structure. The emitted light is collected to generate an intensity map. On the upper right is a dark-field STEM image of the molybdenum diselenide nanodot embedded inside tungsten diselenide. The contour of the nanodot is marked by dotted green lines. On the lower right is an artificially colored light emission intensity map of the same region, with the localized emission from the nanodot clearly visible.
