Graphene Photodetectors

Goals

Develop a better understanding of the effects of photon energy on the electrical properties of graphene.

Issues Involved or Addressed

There is a need for flexible and lightweight Infrared (IR) sensors. IR sensors are fundamental in communications, imaging, and temperature sensing. Recently, researchers have attempted to use graphene in IR sensors. Graphene’s unique properties allow it to have high responsivity in the IR range. Current IR sensors achieve high image quality by altering the intrinsic properties of materials. Yet, fabrication of these materials is costly and demands rigorous processing because the bandwidths of these materials are limited, the sensors require multiple captures at different frequencies to produce a clear picture. Another problem with current sensor materials is low thermal conductivity. This requires the user to maintain complex cooling systems to increase the quality of the response. This research will aim to create operable and performant graphene photodetectors.
