Photocurrent generation in semiconducting and metallic carbon nanotubes

Clear evidence is presented for the origins of photocurrent generation in metallic and semiconducting carbon nanotubes — photocurrent is found to be mainly generated by photothermal and photovoltaic effects in metallic and semiconducting carbon nanotubes, respectively. This finding will enable the engineering of highly efficient carbon-based photodetectors and energy-harvesting devices.
