Fig. 5: CDW characterization of (NaOH)0.5NbSe2 and NbSe2.

a The temperature-dependent Raman spectra for (NaOH)0.5NbSe2. b Temperature dependence of the amplitude mode intensity ICDW for (NaOH)0.5NbSe2 and reported monolayer NbSe2 results. c, d The angular-dependent magnetic torque under various temperatures for bulk (c) NbSe2 and (d) (NaOH)0.5NbSe2. The color mapping in the figure represents the torque value.
