Fig. 4: Electronic property evolution of 2D MoS2.
From: Bidirectional and reversible tuning of the interlayer spacing of two-dimensional materials

a PL spectra of Ce–MoS2 with different interlayer spacing induced by the intercalating and eluting of Pt single atoms. Bottom, the PL spectrum evolution of Pt-intercalated Ce–MoS2 with Pt concentration increase. Top, the PL spectra evolution of Pt-eluted Pt, Ce–MoS2 with Pt concentration decrease. b, c calculated unfolded band structures of Ce−MoS2 b and Pt, Ce−MoS2 c. Eg, bandgap.
