MoveOn

The richness of optical and electronic properties of graphene attracts enormous interest. Graphene has high mobility and optical transparency, in addition to flexibility, robustness and environmental stability. So far, the main focus has been on fundamental physics and electronic devices. However, we believe its true potential to be in photonics and optoelectronics, where the combination of its unique optical and electronic properties can be fully exploited even in the absence of a bandgap, and the linear dispersion of the Dirac electrons enables ultra-wide-band tunability. Graphene absorbs photons effectively in visible and infrared frequencies and can be used as photon detector. The aim of this project is to develop a simple graphene based photo-detector. Metallic nanoparticles will be used to enhance the response.

Task

1. Fabricate graphene photo-detector 2. Characterize graphene photo-detector

Requirements

1. Interested in re-search, 2. Prior courses in fundamental physics (e.g., Electromagnetic Fields and Waves, photonics, Optoelectronics). 3. Willing to work in a Clean-Room.
