Annotation

The factors that influence the rise time of the photodiode are investigated and analyzed. Using the obtained results, a photodiode based on a high-ohmic silicon of p-type conductivity with a minimized rise time has been developed. The proposed construction. contains a contact on the back of the crystal of a photodiode, which is not continuous, but has a hole. Such a hole is the projection of a photosensitive element on the reverse side of the crystal of a photodiode. The value of the rise time of this photodiode is no more than 9 ns compared to 37 ns in the FD-255 A analogue.
