Electro-optical synergy on plasmon-exciton co-driven surface catalytic reactions

T
he monolayer graphene-Ag nanoparticles hybrids system is fabricated as the electro-optical coordinated controlled
substrate of Surface-Enhanced Raman Scattering (SERS) spectroscopy. Plasmon-exciton coupling interactions of this
hybrid system are systemically investigated and applied in the field of surface catalytic reactions, manipulated by the electro-
optical synergy. Our experimental results demonstrate that plasmon-exciton coupling interaction co-driven surface catalytic
reactions can not only be controlled via plasmon-exciton coupling, but also by gate voltages and electric current (or bias
voltage). The gate voltage can tune the Density of State (DOS) of hot electrons and electric current can make the hot electrons
with higher kinetic energy. Both of them can significantly promote plasmon-exciton co-driven surface catalytic reaction. Our
electro-optical device based on plasmon-exciton coupling can be potentially applied in the fields of sensor, catalysis, energy
and environment.
