Most infrared photodiodes are made of InGaAs, a material that is neither CMOS compatible nor good for the environment. Here’s an alternative.

Of course, if the IR emitter in the proximity sensor were running all the time ... to oscillating due to the inherent capacitance of the photodiode, so there’s a damping capacitor in the ...

That means there would be major benefits from improving the efficiency of infrared sensors, such as photodiodes. Researchers at Aalto University have developed a new type of infrared photodiode ...
