Figure 10. Schematic representation of the formation of 2D MoS₂ (A)^[57]. SEM images (flakes were vacuum filtered on an aluminum oxide membrane) and AFM image of 2D MoS₂ (inset: histogram of the number of layers of 2D MoS₂ measured from AFM images) (B_1-2). PL spectra of bulk MoS₂ and 2D MoS₂ (B₃). TEM images of MoS₂ quantum dots (B₄)^[59].
