Tungsten Disulfide schematic

Crystalline large area WS2 have been grown directly on SiO2/Si substrates. The top left panel exhibits a high resolution transmission electron microscopy (HRTEM) image of the edge of a single-layer WS2 film. The top left panel depicts a schematic representation of the as grown WS2 film. A photograph of a WS2 film transferred onto a substrate is shown on the right panel, exhibiting the high contrast of the WS2 over SiO2/Si (films are cyan in color).
