We report on the study of electron–phonon interaction in monolayer MoS2 in polarization-resolved Raman scattering experiments as a function of the excitation laser energy (1.96–2.03 eV). In complementary reflectivity contrast measurements we determined the temperature evolution of the A exciton resonances. We found that when excitation laser energy is tuned across the A exciton level the second order ‘b′ mode shifts almost linearly to lower frequency with the rate equal to –78 and –70 cm−1/eV at T = 7 and 295 K, respectively, which is about twice higher rate than those reported in the previous studies of monolayer MoS2 but very close to the relevant rate recorded for bulk MoS2. We interpret this effect as related to the difference of concentration of two dimensional electron gas.
