Extended Data Fig. 2: Temperature-dependent PL spectra of IX from sample 1.

From: Enhanced interactions of interlayer excitons in free-standing heterobilayers

Extended Data Fig. 2

Zoomed in temperature dependent PL spectra with fitting curves for interlayer exciton peaks: IX1 (blue), IX2 (red) and IX3 (green), from free-standing heterobilayer sample (sample 1, close-to-zero twist angle). Black and dark yellow curves are experimental data and accumulative fitting curve, respectively. A 532 nm CW laser was used for excitation and the power used was 8.83 µW.
