Electronic excitation mechanisms in strained 1 L-MoS2. (a) HHG spectrum of primitive 1 L-MoS2 from TDDFT calculation (red) and its comparison with the experimental measurement (purple). (b) Dependence of HHG intensity on the applied strain, and the absolute values of slope corresponding to representative harmonics. (c) Number of electrons excited to the conduction bands during the laser illumination. The inset shows the maximum value of excited electrons (fs) as a function of strain. (d) Distribution of the photoexcited electrons in Brillouin zone at fs under three strain conditions.
