In this work we demonstrate a preparation technique for hybrid Single Walled Carbon Nanotube - Quantum Dot (SWCNT-QD) photosensors. We investigated photogating effect, fast and slow photoresponse mechanisms observed in the response. The photoresponse of the device depends on the thickness of QDs and gate voltage, also how the photoresponse can be further increased by heat treatment.
Great effort has been directed into modifying the electrical properties of produced carbon nanotubes by chemical doping and – in parallel – into controlling their chirality. We present a new approach to synthesizing nitrogen‐doped single‐walled carbon nanotubes (SWCNTs), based on gas phase floating catalyst CVD. The nitrogen content in the tubes was verified by transmission electron microscopy/electron‐energy...
