High-Performance Si APDs Excelitas

WebJan 1, 2009 · When the APD is reverse biased, most of the voltage is dropped across the n +p junction. Because of the higher level of doping in the n + layer, the depletion region extends into the p layer, and with enough reverse bias reaches the intrinsic region. This is the basis of the “reach-through” APD structure that we discussed previously. WebNov 1, 2003 · The avalanche photodiode (APD) is a high-performance and compact light sensor recently applied in various fields of experimental physics. Among several types of APDs, the reach-through APD offers an advantage in direct X-ray detection, thanks to its thick depletion layer (⩾ 100 μ m) in front of the amplification Web(2) The reach-through APD, commercial versions of which have been available for 20 yr, is a device that is fully depleted and designed to have two distinct field regions: a relatively wide region (30-150 m, depending on application) of relatively low field (- 20,000 V/cm) in which light is absorbed and flow audiobook
