Figure 1

Nanohybrid s-SWCNT/Cyt c photodetector and its operation mechanism.

a, Schematic of a s-SWCNT/Cyt c building block with Cyt c. b, AFM image of individual s-SWCNT/Cyt c building blocks dispersed on a SiO2/Si substrate. The inset shows the cross section profiles of two s-SWCNT/Cyt c building blocks under the marked line (cyan) in Fig. 1b. c, Optical absorbance spectra of the pure Cyt c, s-SWCNT and the s-SWCNT/Cyt c nanohybrid solutions, respectively. d, Schematic diagrams of s-SWCNT/Cyt c nanohybrid films (upper) and the band-edge offset across the s-SWCNT/Cyt c interface (lower) for exciton dissociation. e, Diagram of the IR photodetector device schematic on SiO2/Si substrate with two Au/Ti electrodes.
