Photoresponse and external quantum efficiency of the s-SWCNT/Cyt c nanohybrid.

a, Electric current of the s-SWCNT/Cyt c devices under dark and NIR illumination as a function of bias voltage at various incident NIR power density from 15 to 350 mW/cm2. b, Bias voltage dependence of the photoresponsivity at various incident NIR power density from 15 to 350 mW/cm2. c, External quantum efficiency as a function of incident NIR power density. The inset shows the quantum efficiency versus bias voltage under 15 mW/cm2 NIR light. d, The normalized photocurrent-to-dark current ratio (NPDR) as function of the bias voltage.
