I made 2D material using CVD and measured it using Raman spectroscopy equipped by Circular polarized light system, as I know (calculate the Raman tensor) , the Ag mode if the helicity is same (sigma ++/sigma - -) the intensity will emerge, and if the helicity is different (sigma + -/ sigma - +) the intensity will be vanish. in my case I got the intensity of different helicity is half of the intensity of same helicity, why did this happen?

Dear Ikhwan Nur Rahman , could you tell us more about your setup? What laser wavelength you're using, the type of sample (is a TMD which one) and also how you're applying the circular polarization?
