If different manufacturers use different patterns ... To get very high gain, the circuit becomes prone to oscillating due to the inherent capacitance of the photodiode, so there’s a damping ...

Researchers developed a single photodiode sensor that detects full-color light using perovskite materials, impedance data, ...

A G-M tube is not the only game in town though, and even the humble photodiode can be pressed ... so the whole circuit is contained in a diecast box with a foil window to allow radiation to ...
