The negative sign here indicates that the SHG has the opposite circular polarization from that of the fundamental light. Determined by the selection rule, such a high helicity value is preserved because SHG is an instantaneous process and free of any intervalley scattering processes A dominant SHG intensity peak is observed at a pump energy of 1.
The excitation energy was 1. The significant negative helicity at the 1s resonance confirms the existence of a rigorous selection rule for SHG. Full size image In contrast to the SHG selection rule at the 1s resonance, TPL displays a completely opposite valley-dependent selection rule at the 2p resonance. In an excitation energy scan Figure 3a , a dominant resonance was observed at 1.
The TPL helicity was measured to be More interestingly, we observed a TPL resonance in the emission helicity at the 2p peak Figure 3b inset , confirming our theory that the EAM imposes an additional selection rule on the optical transition. The relatively low helicity value observed here is due to the strong intervalley scattering upon the injection of such high energies Away from the 2p resonance peak, we always observed nonzero TPL with lower energy excitation, as shown in Figure 3a , indicating the presence of several non-excitonic states with p components below the 2p state.
This background cannot originate from the re-absorption of the SHG emission because the emission helicity is positive. A dominant TPL intensity peak resonance is observed under 1. A helicity resonance is observed at the 2p excitonic level.
Away from the 2p resonance, the TPL helicity decreases with increasing excitation energy due to the energy-dependent intervalley scattering. Full size image Subsequently, we further examined the valley-exciton locked selection rule by performing time-resolved TPL measurements. After the initial two-photon absorption and the formation of 2p valley excitons, two subsequent processes occur: the 2p excitons relax to 1s excitons, and these 1s excitons recombine. Here, we conducted time-resolved TPL measurements at the 2p resonance, and the signal was detected by a synchroscan streak camera with an overall time resolution of 2 ps.
Therefore, the time-resolved TPL trace includes only relaxation and recombination Figure 4a. Regarding the sub-ps 2p—1s relaxation, which is reported here in 2D TMDC for the first time, it was further verified by time-resolved PL measurements under near-resonance one-photon excitation Figure 4b.
The rising feature in this curve is much sharper compared with that under 2p resonant two-photon excitation, which indicates more rapid relaxation because of a smaller energy gap. Indeed, our fit shows that the relaxation time to the 1s exciton edge in this case is less than fs the fastest process can be extracted from convolution fitting.
This confirms our observation of a measurable sub-ps 2p—1s relaxation due to the large energy gap between the 2p and 1s excitonic levels. Excited carrier relaxation can typically follow three possible pathways: carrier—carrier scattering, carrier—phonon scattering, and radiative emission. Carrier—carrier scattering is predominantly dependent on carrier density. However, as we varied the pump intensity, no significant change in the dynamics was observed see Figure 4c.
Therefore, carrier—carrier scattering is unlikely to account for the sub-ps relaxation here. Meanwhile, radiative emission from the 2p—1s transition can be excluded because the transition rate is not expected to be as fast as the sub-ps level. Given the comparable densities of states and transition matrix amplitudes calculated using the GW method 9 , 21 , one should expect the 2p—1s transition time to be similar to the 1s exciton radiative lifetime. Therefore, it is very likely to be attributable to exciton—phonon scattering.
This is further confirmed by the broader linewidth of the 2p exciton see Figure 3a. According to the uncertainty principle, this corresponds to an additional linewidth broadening of greater than 30 meV compared with the 1s exciton.
This is consistent with our observation, which indicates 40 meV of additional broadening.
