Toward the Super Temporal Resolution Image Sensor with a Germanium Photodiode for Visible Light
The theoretical temporal resolution limit tT of a silicon photodiode (Si PD) is 11.1 ps. We call “super temporal resolution” the temporal resolution that is shorter than that limit. To achieve this resolution, Germanium is selected as a candidate material ...
