Characterization of mechanically exfoliated WSe2 monolayer. a Optical microscope image and b PL mappings of WSe2 monolayer. c PL spectra along the white dotted line in b, inset: average photoluminescence spectrum and fitted curve. d Raman mappings of WSe2 monolayer. e Raman spectra along the white dotted line in d. Inset: average Raman spectrum and fitted curves. f Peak frequency shift of the in-plane \(E_{2g}^{1}\) mode. Inset: Schematic atomic displacement of in-plane mode. Scale bar in a is 10 μm, others are 5 μm
