Fig. 4: Correlation on the dark current density and the noise current.

From: Ultralow dark current in near-infrared perovskite photodiodes by reducing charge injection and interfacial charge generation

Fig. 4

Noise current measured under reverse bias (−0.5 V) vs. dark current density of PPDs with different EBL-perovskite combinations, as indicated in the legend. Colored circles and whiskers are median values and standard deviation, respectively, extrapolated in the frequency region between 10–100 Hz (i.e., where noise is dominated by white noise) (see Supplementary Fig. 14). The shot noise limit is also plotted for comparison (dashed line).
