Evaluation of carbon nanotubes for THz photomixing

Photomixers commonly used to generate THz radiation cannot generate more than a few microwatts of THz power and therefore enhancement of power remains as a challenge. New materials such as carbon nanotubes offer a set of properties that possess the potential for power enhancement for photomixing. This paper evaluates these key properties for photomixing purposes and estimates the increase in output power in comparison to conventional LT-GaAs photomixers.
