Abstract
We present a wafer scale, laser controlled fabrication method for making large-area, plasmonic dimeron-pillar configuration, using stimulated dewetting of thin silver film on MoS2 covered gold disc. The dewetting of 3-nmthick silver film forms preferential silver islands only on the exposed area of the samples. An enhancement in Raman signal is observed, implying the usage of said surface for surface enhanced Raman scattering (SERS). The fabricated configuration can act as a simple and convenient template for optoelectronic and photonic devices.
