Fig. 3From: A Biaxial Strain Sensor Using a Single MoS2 Gratinga Reflectance spectra of the MoS2 flake as a function of wavelength under different uniaxial strains. b Peak positions of the reflectance spectra of the MoS2 flake under different biaxial strains. Dashed lines represent the fitting curves. Inset: The mapping image of peak positions from the fitting equationBack to article page
