A type of semiconductor detector operated at high voltages. When incident light generates photoelectron from the material, the high voltage across the device accelerates the electron enough to cause avalanche of other electrons, effectively amplifying the signal. An avalanche photodiode could be seen as similar to a solid state photo-multiplier.
