Raman tensor of layered ws2
Webb25 nov. 2015 · Raman investigation of MoSe2 was carried out with eight different excitation energies. Seven peaks, including E1g, A1g, E2g1 and A2u2 peaks are observed … WebbRaman modes becomes parallel polarization and independent on the Raman tensors of involved phonons. We attribute this breakdown of Raman selection rules to the intraband Fröhlich interaction between the isotropic s-state of dark A exciton and scattered phonons. 2 Experimental The samples were prepared from bulk WS 2 crystals onto SiO
