How dopants affect Raman spectra of 2D materials?5 answersDopants have been found to affect the Raman spectra of 2D materials. In the case of Transition Metal Dichalcogenide (TMDC) materials, doping can cause a red-shift or blue-shift of the A1g mode, depending on whether it is n-type or p-type doping. In few-layer tungsten diselenide (WSe2), the reduction of symmetry from 3D to 2D leads to the appearance of new Raman peaks that were previously inactive in the bulk material. The effects of dopants on the Raman spectra of double-wall carbon nanotubes (DWCNTs) have also been studied. Dopants such as bromine and iodine can cause changes in the electron-phonon coupling and the relative intensity of certain Raman bands, leading to a loss of metallic behavior and a dominance of certain tube configurations in the spectra.
