Fig. 4. Tilted (45°) magnetic field—the four mixed excitons states (labeled 1, 2, 3, 4) in MoS₂ monolayer revealed by magneto-photoluminescence.

a Color map of the variation of the PL intensity as a function of B; b PL spectra for magnetic fields from 15 to 30 T showing the emergence of the two lowest energy states 1 and 2 (mainly with gray and dark components). c Magnetic field dependence of the energy of the four mixed exciton states. The full lines are fits to the model described in the text. The notations dark exciton (X_D), gray exciton (X_G) and bright excitons (X_B) are only strictly valid at 0 T. d Same fitting results than in c. The size of each symbol is proportional to the weight of each component (the two bright component X_B+ and X_B− and the two dark component X_G and X_D) (see Supplementary Note 7 for the calculation of the weight of the four components at high field).
