8118 1056 WS2 nanosheets TEM&AFM The morphological characteristics of the exfoliated WS2 nanosheets were observed by TEM (Figure 1a). The WS2 nanosheets display a wrinkle shape due to partial overlap and folding, and the diameter of the layered nanosheets ranges from 50 to 300 nm. The AFM image in Figure 1b further proves the above-mentioned morphology and size of layered nanosheets, indicating that the thickness of the WS2 nanosheets is about 13 nm.
