avalanche photodiode (APD)
A photodiode that operates with a reverse-bias voltage that causes the primary photocurrent to undergo amplification by cumulative multiplication of charge carriers. Note: As the reverse-bias voltage increases toward the breakdown, hole-electron pairs are created by absorbed photons. An avalanche effect occurs when the hole-electron pairs acquire sufficient energy to create additional pairs when the incident photons collide with the ions, i.e., the holes and electrons. Thus, a signal gain is achieved. [After 2196]

APD
Avalanche Photodetector. The solid-state equivalent of a PMT, usually restricted to operation in the red, near-infrared and infrared part of the spectrum. For photon-counting applications, they are operated in the so-called "Geiger Mode". The device is noisier than a PMT but has greater quantum efficiency. Maximum quantum efficiencies are about 80%.
