Abstract
We focus on less studied effect in SERS of chemical enhancement responsible for selective enhancement of Raman response of different analyte molecules adsorbed on same substrate materials. We incorporate finite-difference time domain (FDTD) simulations to discuss how the design of structures attributes to electric field and absorption of non-metallic SERS system which does not involve surface plasmonic resonance. Comparing to our experimental results, we suggest optimization conditions for chemical enhancement in SERS without involving surface plasmon resonance.
