Figure 20.
(a) Raman spectra of 2L CrI3 acquired at 10 K in the RR and LL polarization channels with an applied out-of-plane magnetic field (B⊥) of 1 T (top), 0 T (middle), and −1 T (bottom), respectively. (b, c) Plots of the Poisson fit amplitude A0 (b) and the 2D e-ph coupling strength α2D (c) as a function of the applied B⊥ in the RR (orange data points) and LL (blue) channels. Solid lines are step (orange and blue in b) and linear (gray in c) function fits to the magnetic field dependence of A0 and α2D, respectively.
