• enables a high SERS enhancement factor when the molecules are excited with the |Ex,y|2 component of the azimuthal polarization. Regarding the photoluminescence spectra measured at the border (bilayer) and center (monolayer) regions of CuPc/MoSe2 with radial and azimuthal polarization (Figure 3b), we
