Fig. 5: Photoredox phase transition using PAH-Li system.
From: Photoredox phase engineering of transition metal dichalcogenides
a, Raman spectra of PAH-Li treated MoS2 with the chemical structure of PAHs. Blue-shaded region denotes redox-matched chemicals. Anthracene-Li (green) and pyrene-Li (purple) show the 1T Raman signature identical to the n-BuLi-treated sample (blue). b, Optical image of phase transition of thick MoS2 by anthracene-Li treatment for 600 s in the dark. c, Optical image of phase transition of thick MoS2 by anthracene-Li treatment for 10 s with 445 nm illumination. Scale bar, 10 μm (b,c).
