Fig. 2

(a) Dark field STEM image of the 2D V2O5 sample, and (b) the atomic resolution iDPC (Integrated differential phase contrast)-STEM image of 2D nanosheets. (c) Raman spectrum of 2D V2O5 nanosheets. (d) AFM topography of 2D V2O5 nanosheets. The height profiles of the nanosheets obtained from the marked positions in the AFM images and the distribution of nanosheetthicknessesare also revealed in the figure. (e) XPS survey spectrum of the 2D V2O5 nanosheets. (f) Core level spectrum of the V2p state.
