Abstract:
The coming together of the fields of nanotechnology and plasmonics has led to new and interesting phenomena. The industrial need for fast, efficient, and miniature devices which constantly push the boundaries on device performance taps into the happy marriage between these diverse fields. Designing devices for real life application that give superior performance when compared with existing ones is enabled by a better understanding of structure-property relationships. Among all the design constraints, without doubt, the shape and size of the nanostructure along with the dielectric medium surrounding it has the maximum influence on the response and thereby the performance of the device. Hence, a careful study of the above mentioned parameters is of utmost importance in designing efficient devices. This research synthesizes and studies the optical properties of nanostructures of different shapes and size. Such an in depth study of the structure-property relationship, particularly the near field enhancement of novel metal, metal-metal oxide nanostructures will lead to potential applications as photocathode materials in next generation light sources.
