We have investigated the spreading of the avalanche process over the area of reach‐through avalanche photodiodes operated in Geiger mode. Avalanche photodiodes (APDs) have been widely studied and effectively applied in commercial, military, and academic fields [] for a few decades.Compared with p-i-n photodiodes, APDs provide higher gain, higher sensitivity and lower detection limit [], so they are mostly well applied in optical communications [], imaging [4, 5], and single photon detection [6, 7] in recent years. Avalanche Photodetector (APD) Principles Ionization coefficient αe ≈αh Ionization coefficient αe >> αh The avalanche process is asymmetric (i.e., the probability for initiating an avalanche is usually greater for one type of carrier than for the other). A 1-D drift-diffusion model is developed for reach-through avalanche photodiodes. The wide intrinsic region makes the PIN diode an inferior rectifier (one typical function of a diode), but it makes the PIN diode suitable for attenuators, fast switches, photo detectors, and high voltage power electronics applications. –Phototransistors are photodiodes with some internal amplification. A comparison between the measurements and the results of a computer simulation suggests that photons emitted from hot carrier relaxations play the dominant role in the avalanche dynamics. 39 The Avalanche Process The drift electrons acquire sufficient energy in the p-layer to impact-ionize some silicon covalent bonds and release EHPs.
