a Measured responsivity as a function of wavelength at reverse-bias of −0.5 V and illumination power of 0.5 μW for green, yellow, and red color channels. b Measured photocurrent as a function of reverse-bias in red color channel at illumination wavelength of 630 nm with illumination power parameterized. Source data for a and b are provided in the Source Data File tabs labeled a and b, respectively.
