WebDec 20, 2024 · This has two beneficial effects in the context of photodiode applications. First, a wider depletion region makes the photodiode more sensitive, as explained in the … WebThe photoconductive gain can be substantially larger than unity, which means that the obtained photocurrent for a given light power (i.e., the responsivity) can be much larger than that of a photodiode. This is possible only because minority carriers reaching an electrode can lead to the injection of additional majority carriers; otherwise, an ...
WebThe recombination of the photo-generated carriers is obstructed by barriers in real space, in configurational space, or in momentum space. Charge persistence is significant for heterojunctions and field-effect structures. Many technologically important impurity complexes — especially in compounds and their alloys — display persistent photoeffects.
