Reach through apd
WebNov 2, 2016 · Three basic structures of SAM-APDs are considered in this work, namely reach-through (i.e., multiplication, drift, and absorption regions are all depleted at normal working bias), non-reach-through (i.e., only the multiplication region is depleted at normal working bias), and close-to-reach-through (a special case of reach-through structures). WebA reach-through APD of a 130 µm thickness can potentially detect soft X-rays below 20 keV with efficiencies greater than 10%. The signal amplification in the APD devices has a good advantage of detecting soft X-rays even at room temperature or at lightly cooled environment[11,12]. Figure 3 presents

WebMay 25, 2009 · An avalanche photo diode (APD) is a compact photon sensor with an internal gain of 100. We have developed an X-ray/gamma-ray detector using a back-illuminated reach-through APD (5x5 mm {sup 2}) optically coupled with a conventional CsI (Tl) scintillator, which covers typically from 1 keV to 1 MeV. WebMar 11, 2000 · A simple 1-D model of the operation of a reverse reach-through APD has been developed. APD parameters have been calculated using McIntyre approach and presumed doping profile of the APD. Good agreement between calculated and measured parameters for one APD from EG&G was obtained.

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.
