Numerical Study of Electric Field Enhancement in Inverted-Pyramid Gold Arrays with Tunable Spacing

Numerical Study of Electric Field Enhancement in Inverted-Pyramid Gold Arrays with Tunable Spacing

This study presents a comprehensive numerical and experimental investigation of electric field enhancement in inverted-pyramidal gold (Au) array substrates, focusing on variable inter-pyramidal spacing for surface-enhanced Raman scattering (SERS) applications. We conducted a series of finite element...
