Fig. 2: Characteristics of the organic infrared photodiodes.
From: Noise and detectivity limits in organic shortwave infrared photodiodes with low disorder

a Dark current density versus applied voltage. b Imaginary versus real impedance. c Noise current density measured by a power spectrum analyzer. The equipment background noise is included as the gray line. d Photocurrent density versus voltage measured under a 1.2 mW/cm2 continuous light with λ = 1100 nm. e External quantum efficiency and f specific detectivity measured under a monochromatic light modulated at 400 Hz. The devices in b, c, e, and f are biased at 0 V.
