Plasmonically augmented broad spectral photodetection in metamaterials based CdS thin film heterostructure

Plasmonically augmented hot electron photodetection enable materials to exhibit new optical functionalities for the wavelengths beyond their detection limit and hence emerges as a new field for potential application such as photovoltaic's, photo-catalysis, photodetection, nanoscale imaging, photo-induced phase- transition etc. Metamaterials are artificial rationally designed properties which can allow both field component of light to be coupled to meta-atom, enabling entirely new optical properties and exciting applications. Here, we have studied the electrical characterization of fabricated plasmonic nanostructure's called as metamaterials (e- beam fabricated) integrated robust CdS film based broad spectral photodetector (visible to NIR region).
