Decorating MoS₂ 2-D materials with metal nanostructures for sensor applications

The monolayers of 2D-MoS₂ have demonstrated distinctive electronic, optical, and catalytic properties. These 2D materials, with and without plasmon enhancement are studied and explored extensively for nanodevice applications ranging from bio/chemical sensors to medical monitors and photovoltaics. Plasmonic resonances strongly depend on the size, shape, spacing, and interaction of metal nanoparticles with semiconductor nanostructure. A lot of resources as well as efforts are required to realize plasmonic resonator devices and optimization with different shapes and sizes. In contrast, device modeling and simulations offer a much economical substitute to tackle such challenges. I am presenting models and simulations of nanoparticle plasmonic resonators decorated on 2-D MoS₂ monolayers for sensing applications.
