Abstract
Metamaterials (MMs) research has gained widespread attention in the past decade due to advances in fabrication methods, the realization of its interesting optical properties, and the potential applications. It is a technology that combines the physics of plasmonics and optics. MMs can be used as optical components that are simultaneously thin and flat, called metasurfaces; these materials are useful for the integration with other electrical devices such as transistors. One of the main challenges of this field is in the fabrication methods. This project demonstrates the lateral control of carrier concentration in doped silicon, and proposes a novel method of creating self-assembled MMs. The results show that silicon can be used as a mid-infrared plasmonic material. Based on successful simulations that demonstrate the optical response of gold split-ring resonators, a way of making MMs by using strain-induced semiconductor nanotubes is introduced.
