(a) Raman spectra of 2L CrI₃ taken at 10 and 70 K with an excitation wavelength of 633 nm. Solid orange lines are fits to the raw Raman spectra, using a sum of N Lorentzian profiles and a constant background, . (b) Histogram plot of the fitted Lorentzian mode intensity (A_N) as a function of N at 10 and 70 K. Solid curves are fits of the peak intensity profiles to the Poisson distribution functions, . (c) Plot of 2D e-ph coupling constant (α_2D) as a function of temperature. The dashed vertical line marks the magnetic onset T_C = 45 K.
