“…Optoelectronic devices based on carbon nanotubes (CNTs) and graphene nanoribbons (GNRs), namely, GNR/CNT-based cells, carbon-based phototransistors, and carbon-based photodetectors, have attracted significant interest in recent years [ 1 , 2 , 3 , 4 , 5 ]. Indeed, CNT/GNR-based phototransistors have gained keen focus owing to their promising features such as the unique light–CNT/GNR interaction, high photoresponsivity, fast response, high detectivity, high photosensitivity, extensive detection range, and especially, the low noise in comparison to the conventional photodiodes [ 6 , 7 , 8 , 9 , 10 ]. Most of these promising features are attributed to the unique characteristics that the CNTs and GNRs exhibit in terms of the physical, electrical, optical properties and are synergically correlate with their atomistic structures [ 11 , 12 ].…”
