Raman spectra of bilayer MoS2 under uniaxial strain. a Raman spectra of bilayer MoS2 as a function of uniaxial strain. From left to right, the shear, breathing, split E g, and A 1g modes are denoted by the triangle, square, diamond, and circle symbols, respectively. b The peak positions for intralayer phonon modes (upper panel) and interlayer shear and breathing modes (lower panel) as a function of uniaxial tensile strain. Error bars in strain come from the uncertainty in the estimate of the strain using the equation ε = t 0 θ/L 0. The error bars in Raman shift are defined by spectral resolution of the spectrometer
