Here,a novel Au Wedge-enhanced Raman spectroscopy (WERS) substrate is proposed.The electric field enhance-ment factor and the effective mode field radius with varying geometry parameters are investigated.The proper excita-tion wavelength 633 nm is obtained.The practical application of WERS substrate is discussed.The Au WERS not only can provide a continuous extremely highly localized electric field as surface-enhanced Raman scattering (SERS)hotspots,but also can offer 10 orders of magnitude of SERS enhancement factor.The corresponding results reveal that WERS substrate will be widely applied in optics,biology,chemistry and other fields.
