Simulations of Nanostructure Plasmonic Resonators

Semiconductor nanostructures 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 depends 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. To solve this problem in most economical and reliable mode, is to use Maxwell equation solver which helps in simulating the nanoparticles as surface plasmon resonator on the top of semiconductor nanostructures. The sharp features as well as the nanoparticle asymmetry is usually used for reported the enhancement of the electric field. To enhance the absorption rate as well as the photocurrent signal, I report the simulation the electrical field profile for spherical, cylindrical, and bipyramidal nanoparticles (of different materials) and model the interaction of these nanoparticles with semiconductor nanostructures.
