Lecture 12: Photodiode detectors

7 Choice of photodiode materials A photodiode material should be chosen with a bandgap energy slightly less than the photon energy corresponding to the longest operating wavelength of the system. This gives a sufficiently high absorption coefficient to ensure a good response, and yet limits the number of thermally generated carriers in order to attain a low "dark current" (i.e.
