From: All inkjet-printed electronics based on electrochemically exfoliated two-dimensional metal, semiconductor, and dielectric

Fig. 2

a Schematic illustration of the electrochemical exfoliation process. b Atomic force microscope (AFM) image of the exfoliated MoS2 nanosheets. White line in the image shows the height profile. c Histogram showing the lateral size distribution of the MoS2 nanosheets. d Raman spectrum of the MoS2 nanosheet film measured with a 532 nm laser. e Stroboscopic images showing the time evolution of the MoS2 droplet morphology after jetting. f–i Optical microscope and AFM images of dot-patterned MoS2 films (diameter: 70 μm) resulting from different ink formulations. One printing pass was used.
