Plasmonic Bi-Cavity Nanostructure for Efficient Light Collection and Localization
Vitor Monken, Raul Correa, Hudson Miranda +5
Tip-enhanced Raman spectroscopy (TERS) typically relies on high-NA excitation to generate a strong axial field at the tip apex, which shortens the working distance and constrains s…
