Enhancement of electric field and Raman scattering by Ag coated Ni nanotips: Dexian Ye, Stephen Mutisya, and Massimo Bertino
Localization and enhancement of electric field by Ag-coated vertical Ni nanotip arrays were studied by using finite-different time domain calculations. With the 30 nm thick Ag coating, the nanotips can localize and enhance the electric field to more than 10 times under the excitation of TE-polarized ... [Appl. Phys.
