(a) Evolution of the Raman spectra of the MoS2 monolayer on the PDMS substrate at different temperatures. The dashed line is the guide of the peak centers. (b) The temperature-dependent \({\text{E}}_{2\text{g}}^{1}\) Raman peak shift measured on the MoS2 monolayer prior to tensile strain. (c) Power-dependent \({\text{E}}_{2\text{g}}^{1}\) Raman peak shift measured using different optical lens on the MoS2 monolayer prior to tensile strain. (d) The temperature-dependent \({\text{E}}_{2\text{g}}^{1}\) Raman peak shift measured on the MoS2 monolayer under the tensile strain of 6.3%. (e) Power-dependent \({\text{E}}_{2\text{g}}^{1}\) Raman peak shift measured using different optical lens on the MoS2 monolayer under the tensile strain of 6.3%.
