Abstract: Graphene has emerged as a promising material for photonic applications fuelled by its superior electronic and optical properties. However, the photoresponsivity is limited by the low absorption cross-section and ultrafast recombination rates of photoexcited carriers. Here we demonstrate a photoconductive gain of ?105 electrons per photon in a carbon nanotube-graphene hybrid due to efficient photocarriers generation and transport within the nanostructure. A broadband photodetector (covering 400-1,550 nm) based on such hybrid films is fabricated with a high photoresponsivity of >100 A W-1 and a fast response time of -100?s. The combination of ultra-broad bandwidth, high responsivities and fast operating speeds affords new opportunities for facile and scalable fabrication of all-carbon optoelectronic devices. © 2015 Macmillan Publishers Limited.
