Figure 6: Evolution of Raman spectra due to laser radiation pressure.
From: Graphene Oxide Demonstrates Experimental Confirmation of Abraham Pressure on Solid Surface
(a) Raman spectra at different laser power ranging from 0.028 mW to 12.78 mW. (b) Plot of D & G peak intensity with the variation of laser power. The difference in rate of change in peak intensity distinguishes bending and etching phenomena below and above the breaking point respectively (c,d) Change in Raman peak position (both D and G band) with respect to laser power. Both D and G peak shows similar trends of change in position with the laser power. Inset shows the zoomed view of the breaking point showing the change in Raman peak position with the laser power ranging 0.67–1.59 mW.
