Fig. 2: Comparison of the Raman spectra between the bulk and bilayer α-RuCl3.
From: Multiple spin-orbit excitons in α-RuCl3 from bulk to atomically thin layers
a Raman spectra of bilayer α-RuCl3 at selected temperatures. The spectra are vertically shifted for clarity. b Temperature dependence of the Fano asymmetry for the bulk and bilayer α-RuCl3. The dashed lines are guides to the eye. c Temperature dependence of the integrated Raman intensity over the middle energy of ω = 8.4 −16.1 meV for the bulk and bilayer α-RuCl3. The solid lines fit to a sum of the two-fermionic and bosonic functions.
