Evaluation of complementary metal-oxide semiconductor based photodetectors for low-level light detection

Current low-level light detection technologies for biomedical applications such as DNA microarray sensors use charge-coupled devices or photomultiplier tubes which cannot be easily integrated with electronic circuits on a chip. Complementary metal-oxide semiconductor (CMOS) image sensors do allow for the integration of photosensitive and signal processing elements on the same chip. However, more research is required if optimized low-level light …
